Research Grants

Foundation Title:

Obtained more than 30 grants, among them 2 DAAD , 3 INTAS, 2 ANSEF, 1 fellowship, 3 visiting professorship, ~ 20 for visits and collaboration.

Other

Obtained some new results (nearly 15) related to the basic concepts in mathematics such as: arbitrary algebraic plane curve, complex polynomials, analytic and meromorphic functions in a given domain; enough smooth plane curves, real and complex functions of one and two variables; solutions of large classes of differential equations.

Some of these results have no predecessors. Others generalize widely preceding studies in the frames of Hilbert problem 16 in the real algebraic geometry, of Nevanlinna and Gamma-lines theories in the complex analysis, of Poincaré theory in the ODE.

A part of the mentioned above results was presented in my plenary lecture given at the 6th ISAAC Congress (2007) and published in

Barsegian G., *Some interrelated results in different branches of geometry and analysis*, p. 3-33, in book "Further progress in analysis. Proceedings of the 6th International ISAAC Congress", editors H. Begehr, O. Celebi and R. Gilbert, World Scientific, 2009.

The research papers and preprints were published in Armenia, England, Germany, Georgia, Honk Kong, Hungary, India, Italy, Poland, Romania, Russia, Singapore, Spain, Switzerland, Japan, Yugoslavia, USA.
