Proceedings of Yerevan State University 2003 #1(200) About
Published since 1925. Currently the peer-reviewed works on natural sciences, mathematics and informatics are published here in Armenian, Russian and English languages.
"Proceedings of the YSU" is published three times a year. The journal presents original articles containing new results of theoretical, experimental and applied research, carried out in YSU or other Armenian and foreign scientific centers.
The first Editor in Chief in 1967-1972 was academician of Armenian AS Hovhannes H. Chaltikyan
Scince 2009 the Journal is publishing in three series
