Reforms in Czechoslovakia in the 1960s came to an end in the spring of 1968 when Soviet troops entered the country. Czechoslovakia became a federal republic, the Czech part and the Slovakia part becoming the Czech Socialist Republic and the Slovak Socialist Republic, respectively. Each had their national parliaments and governments and this federal process led to the Union of Czech Mathematicians and Physicists splitting into a Czech part and a Slovak part. The **Union of Slovak Mathematicians and Physicists** split off from the old Union in 1969 at the fifth congress of the Union of Czechoslovak Mathematicians and Physicists. The name of the Union in the Slovak language is 'Jednota slovenských matematikov a fyzikov'.

The Union of Slovak Mathematicians and Physicists comprises of two sections, the Slovak Mathematical Society, and the Physical Pedagogical Section. It is a member of the European Mathematical Society, and of the International Mathematical Union. It is financed partially by the annual membership fees, partially by financial support from the Ministry of Education of the Slovak Republic and from the Slovak Academy of Sciences. The following description of the Union is taken from [1].

The Union of Slovak Mathematicians and Physicists is a voluntary association of teachers, scientific and professional staff in the field of mathematics, physics and related disciplines. It was founded in 1969 as part of the "Union of Czechoslovak Mathematicians and Physicists", established in 1921 from the original 'Association for Free Lectures in Mathematics and Physics', founded in 1862. Since 1993, the Union of Slovak Mathematicians and Physicists has been operating as an independent organization in the Slovak Republic but continues to work closely with its partner organization in the Czech Republic the Union of Czech Mathematicians and Physicists. The Union of Slovak Mathematicians and Physicists operates as a science unit at the Slovak Academy of Sciences. The headquarters of the Union is the Faculty of Mathematics, Physics and Computer Science of Comenius University in Bratislava. The Union operates in the Slovak Republic through its regional branches. The Union has sections consisting of the Slovak Mathematical Society, the Physical Education Section and the Scientific Board of the Union of Slovak Mathematicians and Physicists for Mathematics. The main aims and tasks of the Union are as follows:

(ii) It extends knowledge gained in the field of scientific research and encourages scientists to actively collaborate in the development of mathematics and physics.

(iii) It provides assistance to schools in raising the level of teaching mathematics, physics, mathematical computer science and descriptive geometry.

(iv) Special attention is paid to developing the talents of pupils and students in mathematics, physics and related sciences, in particular through lectures, seminars, summer and winter schools, and courses.

(v) It professionally guarantees student competitions with a focus on mathematics, physics and related science, in particular the Mathematical Olympiad, tournaments and correspondence seminars.

(vi) It contributes to raising the professional level of its members with special regard to young workers.

(vii) It provides its members with assistance in their scientific, pedagogical and other professional work.

(viii) It promotes the results of science at both domestic and international forums.

(ix) It organizes national and international conferences, seminars, scientific symposia, lectures, discussions and other professional events.

(x) It performs its own editorial work and produces professional literature to help its members, schools, scientific workplaces and the professional public.

(xi) It performs teaching and educational activities for the public in order to increase the mathematical and physical literacy of society.

Many international conferences are held which are organised by a number of different societies and universities including the Union of Slovak Mathematicians and Physicists. For example they are co-organisers of the Czech and Slovak International Conference on Number Theory, the 23rd such conference having been held in 2017. They cooperated in the organisation of International Mathematical Conferences on the occasion of 50th anniversary of the foundation of the University of Zilina in 2003. For example, the Conference on Differential Equations and Applications in July 2003, and the Conference on Geometry and Graph Theory, also in July 2003. Following this, they have been involved in the organisation of the Conference on Differential and Difference Equations held in 2006, 2008, 2010, 2012, 2014 and 2017. Another conference series which they collaborate in organising is the Equadiff series of biannual conferences on mathematical analysis, numerical approximation and applications of differential equations held in rotation in the Czech Republic, Slovakia and Western Europe. The first was held in Prague in 1962 and the 26th was held in Bratislava, Slovakia, in July 2017. The ALGORITMY (Algorithms) series represents the oldest Central-European series of international high level scientific meetings devoted to applied mathematics and numerical methods in computational sciences and engineering. It has been traditionally organized in the High Tatra Mountains, Slovakia, with the 20th conference being held in Podbanske in 2016. These are organised by the Union of Slovak Mathematicians and Physicists in cooperation with the Slovak University of Technology in Bratislava, Comenius University in Bratislava, and the Slovak Academy of Sciences.

The Union of Slovak Mathematicians and Physicists honours people by making them Honorary Members of the Union. It also gives Excellence in Teaching Awards, and a Special Award. A 'Prize for Young Mathematicians' is awarded for outstanding young mathematicians under the age of 30.

The following is taken from the report made in 2011 [2]:-

There are about61active mathematicians(15female)working at the Mathematical Institute of Slovak Academy of Sciences and about500mathematicians(200female)working as university lecturers at10universities in Slovakia. The Union of the Slovak Mathematicians and Physicists has650members of which212(45female)are in the Slovak Mathematical Society.

Most Slovak women mathematicians, who are active in the Slovak Mathematical Society or in The Union of Slovak Mathematicians and Physicists, do not see any reason to organize separate activities or create subgroups for women, within or outside these basic organizations. All such activities are perceived more or less based on discrimination and excluding principles, which they find rather dangerous in connection to acknowledgment by the community of mathematicians in Slovakia, as being regarded of less significant, or having no appropriate scientific recognition and professional level.
