I had a happy childhood and a thriving adolescence. My five sisters and I lived in Tunis. We were born in Tunis as well, except for my older sister who was born in Sfax. And my father was the first Sfaxian to emigrate to Tunis, with my maternal uncle and Mr Taïeb Miladi. At that time there was also internal emigration. My father continued to do in Tunis the same job he did in Sfax, namely bookseller. He settled in Rue Sidi Ben Arous and has known generations of Zitounians and Sadikians who frequented his bookstore. He was a known figure of the souks of the Medina, a scholar and an enlightened man who loved books and reading and who transmitted to us this love intact.

As for us [children], at that time, we went out very little and we used to stay home. But I will always keep a wonderful memory of my childhood in the Bardo family house, often in the garden, with my mother, so gentle, so enlightened, so open, so good, and with my sisters and young nephew. From my childhood, I will also remember that our greatest joy, my sisters and myself, was to go into my father's back bookstore to practise our favourite sport: reading! How many books have been devoured!!

... provided Sadikian instruction, that is to say that at the end of the first part of the Baccalaureate (the Baccalaureate was at this time divided into two parts and was obtained at the end of two years), we sat the "Sadiki College Graduation Diploma" examination, which gives an excellent training that is quite bilingual. By the way, during my time at high school, I loved practically all the subjects, whether they were taught in Arabic, or in French, or even in English.

With hindsight, I believe that the reason is that mathematics corresponded more to my character: I adore rigour, precision and honesty. I hate cheating. And this is mathematics! It is an exact and hard science, where one must be precise. Thus, each word has its importance in a mathematical definition: one has no right to remove, add or change a single word. Mathematics requires clarity, and even limpidity. The famous words of Boileau [Nicolas Boileau-Despréaux (1636-1711) was a French poet] are always remembered in mathematics: "What is well conceived is clearly stated, and the words to say it flow with ease." In mathematics, one learns to become fair by treating all cases equally, and one learns to become humble and to move away from human vanity by measuring one's own limits in front of the difficulty of the problems to be solved. In mathematics, we want to exclaim: Glory to honesty, glory to clarity, glory to the neat treatment of problems! Down with confusion, down with obscurantism, down with deceit! And that's why I chose mathematics. However, although mathematics helps to make a person a good person, it sometimes fails to do so (otherwise all world mathematicians would be good persons). I immersed myself, without regret, in the universe of mathematics at the Lycée Carnot ...

At this point, to continue, it was necessary for me to leave Tunis. And there, I had to have the consent of my father, and I had to have a scholarship. Fortunately, President Bourguiba and Minister Mahmoud Messaâdi were enlightened and encouraged the education of both boys and girls. That's why I got a scholarship. As for my father, who was very conservative, he agreed to send his daughter abroad so she could finish her studies. It should be noted that there were, at that time, many "supposedly" modern parents who prevented their daughters from going abroad to study.

And I was deeply afflicted, shocked by this war. Being someone extremely pacifist, I will never be able to understand wars. And I was horrified, saddened by the terrible number of deaths in this war. It was so sad! I was deeply distressed because of my dead compatriots, they should never have been sent to their death ...

When I returned to Tunisia everyone was glad, especially in my family, both maternal and paternal. There, I realized how much the Tunisian people liked studying, as this glorification of studying was unanimous ... But I was also received in great pomp by the officials: by President Habib Bourguiba, by Minister Mahmoud Messaâdi, by national organizations. Why? It so happens that in the female and male population of Tunisia, the very first person who earned her Agrégation in mathematics was a girl, before the boys. So I was the first but it takes a first to everything! So, in addition, the "National Union of Tunisian Women", which was very important, exploited this with a lot of fuss. And I hope that one day one will stop making such a fuss, largely for a simple chronological chance ... And immediately, I was appointed by Messaâdi, who had proposed me a half-service at the Secondary and a half-service at the University in order to have a varied educational experience, according to him. ... In short, it was the good old days when one did not wait for years to be appointed to the public service, and where the candidates willingly accepted what was proposed to them: I fulfilled this task as best as I could.

This wasn't the final stage of my professional career - I missed something: I wanted to continue my studies to the end. In other words, get my doctoral thesis and continue to do mathematics. Effectively, I defended my "doctorat d'état" thesis in 1965, in Paris. This doctorate was the first earned by a Tunisia woman, and perhaps by a Tunisian man. I was, after that, directly appointed to the Faculty of Sciences of Tunis, where I taught until retirement, without ever leaving, without ever holding concurrently another job ... I have trained generations of mathematicians, and some have taken over.

The theorem of Hopf-Rinow, generalised by de Rham, states that for a complete Riemannian manifold the following properties are equivalent: (a) either every geodesic can be continued indefinitely in either direction or else it is closed; (b) every Cauchy sequence is convergent; (c) every bounded subset is relatively compact. In this paper it is shown that the Hopf-Rinow theorem applies to Cartan-Finsler spaces for which the geodesics coincide with the extremals of the length integral.

Following the theory of Finsler spaces as developed by É Cartan [Les espaces métriques fondés sur la notion d'aire (1934)], the author generalises to these spaces theorems previously obtained by Myers for Riemannian manifolds.

Using the Riemannian case as a guide, the author generalises the idea of total scalar curvature to a compact manifold which admits a Finsler structure. She proves that if the Finsler structure contains no conjugate points, then the total scalar curvature is non-positive.

This paper extends some of the most interesting and important results of global Riemannian geometry to differentiable Finsler spaces. The point of view of the author is essentially that of É Cartan; that is, a Finsler space is defined as a structure on the bundle of all non-zero tangent vectors to a differentiable manifold by means of a fundamental function satisfying the usual hypotheses. The methods of investigation are those of the theory of connections in fibre bundles.

If I were, I would have had the Fields Medal or at least a medal ... ten times less important. No, I have only been serious. I have always been serious in everything I have undertaken. I also enjoyed my work and, after all, it is a pleasure to do the work that you love. I have great memories of brilliant students or simply hardworking or good ones, and an excellent memory of colleagues I have worked with often, moreover, as a member of remarkable women's teams... And I hope I have been a good teacher. As for "my reputation", it is due in large part to a mere coincidence in time and chronology of events ... The second remark concerns the first question you asked me where you were talking about Ms Mongia Mabrouk and Ms Zoubeïda Amira. [Mongia Mabrouk was first doctor of Arabic literature and Zoubeïda Amira was first Tunisian director to hold the reins of a high school in Tunisia just after independence.] I salute your love for your foremothers, and I hope that one day too my grandchildren like you will remember me with love ... Indeed, I knew well Ms Zoubeïda Amira, she was the Director of my high school in the Rue du Pacha. What a good Director! And what a good teacher! Since she also taught in parallel Arabic history. I loved her course ... To my former principal and professor, to my father, to my mother, to my elder sister, to the deceased of my paternal family and my maternal family, to Bourguiba, Messaâdi, Sghaïer Ouled Ahmed ... I would say to you all: I have not forgotten you. You made me what I am today. I feel so much gratitude for you. Peace to your souls! (Some may wonder: what is the poet Sghaïer Ouled Ahmed doing in this list of deceased? Well, it is that I address to his memory all my thanks for expressing, so simply, in a verse of his poetry, what I have always felt: the love of country, its verse of poetry helped me to overcome the setbacks of recent times ...). As for me, still alive to day, I say to myself: "Hamdoullah" and I will proclaim until the last minute: Down with terrorism, down with obscurantism, down with confusion, down with deceit! Long live Work, long live Clarity, long live Mathematics and, most important of all: Long live Tunisia!
