University

Subject of cooperation:
Development of new modeling methods in Biomedicine based on discrete-continuous approaches in which biological cells are considered as individual objects, intracellular regulation is modeled by ordinary differential equations, and intercellular concentrations were described by partial differential equations. Application of these methods to modeling of various physiological processes.
Result of cooperation:

Joint research work with A. Bouchnita. Mathematical models and computer programs for describing the coagulation of blood in the stream considering biochemical reactions in the plasma and aggregation of platelets were developed. The terms of normal clot growth and thrombosis were obtained. Two articles are in print this year.

Result of cooperation:

Accurate stability evaluation for the variation of eigenvalues of nonnegative selfadjoint elliptic operators of arbitrary even order when changing the open sets on which they are defined were obtain with P. D. Lamberti, M. Lanza de Cristoforis, Feleqi E. This evaluation is expressed in terms of Lebesgue measure of the symmetric difference of open sets. The boundary terms of Dirichlet and Neumann were analyzed.

Subject of cooperation:
- Conducting joint research in the field of the theory of elliptic operators, noncommutative geometry.
- Publication of joint papers in high-rated journals
Result of cooperation:

Mathematicians of RUDN University (Professor B. Yu. Sternin, Professor A. Y. Savin) with mathematicians of the University of Hannover (Prof. Dr. Elmar Schrohe) analyze actual problems of elliptic theory and noncommutative geometry in joint scientific works. In particular, an explicit uniformization for elliptic operators associated with groups of shift operators was found out. The terms for the Fredholm property of the operators associated with groups of quantized canonical transformations were obtained.
