# The National Academy of Sciences of the Republic of Armenia

### Founded in 1943

Armenia became a constituent republic of the Soviet Union in 1936 and the

The National Academy of Sciences of the Republic of Armenia has five divisions:

It is the Division of Mathematical and Technical Sciences which is most relevant to this Archive, so our first task is to look more closely at it.

The Division of Mathematical and Technical Sciences contains three Institutes and one Section:

Studies in contemporary mathematics in Armenia date back to 1944, when a Section for Mathematics and Mechanics was created within the newly born Armenian Academy of Sciences. The section later developed into the Institute of Mathematics and Mechanics of Armenian Academy of Sciences whose first Director was Academician Artashes Shahinyan (1906-1978), a mathematician well known for his results in complex analysis. Shahinyan, the son of the physicist Aram Shahinyan, became a professor in 1944, a corresponding member of the Soviet Academy of Sciences in 1945 and a full member of the Soviet Academy of Sciences in 1947. The Institute of Mathematics of Armenian Academy of Sciences separated from the combined mathematics and mechanics Institute in 1971. In the early years the investigations carried out in the Institute concentrated on Function Theory. Gradually the sphere of investigations expanded and, as we indicate below, now includes Differential and Integral Equations, Functional Analysis, Probability Theory and Mathematical Statistics.

This present Institute has the following main areas of interest:

This Section, founded in 1992, has the following main areas of interest:

Wave and vibration control in pipeline systems. Transient and stationary mode management in pipeline systems containing mono- and biphasic (fluid, gas) media with pressure fluctuation and flow stabilizers.

We also mention the Division of Physics and Astrophysics which contains an observatory and three Institutes. We give details of the Observatory:

This observatory is located on the slopes of Mount Aragatz, near the village of Byurakan. It was founded in 1945 on the initiative of Victor Ambartsumian, who became its first director. Its main areas of research are: Detection and study of galaxies possessed by active nuclei and other forms of activity, study of extragalactic objects from the First and Second Byurakan spectral surveys, observational and theoretical studies of systems of galaxies, including the compact and wide groups of galaxies, analysis of the influence of activity processes on the objects' evolution. Studies of star formation regions, including the non-stable young objects of our Galaxy, detection and studies of stellar associations and their typical population - non-stable and flare stars, H-alpha emission stars, young stars possessing of various types of activity, including the anisotropic optical jets, detection and studies of nebula, detection and exploration of blue stellar objects and late type stars from Byurakan spectral surveys. Mathematical modelling of actual problems of astrophysics, interpretation of spectra of cosmic objects, theory of radiation transfer in stochastically inhomogeneous media, problems of the observational cosmology, including the formation of cosmic objects belonging to various hierarchical levels and their evolution. Astronomical instrument-making, including the design and building of telescopes and astronomical towers and domes.

**Armenian Academy of Sciences**was founded on 10 November 1943 as a branch of the USSR Academy of Sciences. The founder and first president was Hovsep Orbeli, an orientalist who specialised in the medieval history of the Caucasus area. Orbeli served as president from 1943 to 1947 when he was succeeded by the theoretical astrophysicist Victor Amazaspovich Ambartsumian who held this position until 1993. The modern Republic of Armenia became independent in 1991 after the break-up of the Soviet Union and in 1993 the Academy became the 'National Academy of Sciences of the Republic of Armenia'.The National Academy of Sciences of the Republic of Armenia has five divisions:

The Division of Mathematical and Technical Sciences,

The Division of Physics and Astrophysics,

The Division of Natural Sciences,

The Division of Chemistry and Earth Sciences,

The Division of Armenology and Social Sciences.
