Biography
Graduated from Mathematics and Mechanics Faculty of Novosibirsk State University — 1972. Ph.D — 1981. D.Sci — 2000. Since 1997 I am working as head of researches financed by grants (1997–999, 2000–2002). The subject of researches is Qualitative and structural characteristics of differentiable functions and differential operators.
