XXXV International Enlarged Sessions of the Seminar of Ilia Vekua Institute of Applied Mathematics of Ivane Javakhisvili Tbilisi State UniversityTbilisi, Georgia202121/04/2021-23/04/2021Ilia Vekua Institute of Applied MathematicsOn the integral equations induced from Bers- Carleman-Vekua irregular equations oral

In the report the integral equation of the third kindwhich are associated with the irregular Bers-Carleman-Vekua equations when the coefficients of equations belong to a wide class of functions will be discussed. It is shown that the irregular Bers-Carleman-Vekua equation and the corresponding integrated equations from this class have only a trivial solution in the class of analytic functions of two variables. The existence of a wide class of integral equations is proved, where the non-trivial solution does not existand it is shown that for such equations the Fredholm alternative does not hold.

XXXIV International Enlarged Sessions of the Seminar of Ilia Vekua Institute of Applied Mathematics Tbilisi, Georgia202016/09/2020-19/09/2020 Ilia Vekua Institute of Applied Mathematics On the special case of the boundary value problem for Carleman-Bers-Vekua equation oral

The Riemann-Hilbert boundary problem (linear coupling problem) for the Carlemmann-Bers-Vekua equation when the transition function G (t) is given by a circle and has zeros and poles was discussed in the report. We have been presented a necessary and sufficient condition for solving the problem, as well as have been written the solution analytically.

The special case of the linear conjugation nonhomogeneous boundary value problem for CarlemanVekua irregular equation when the boundary function has zeros and poles at some points of the boundary curve is considered. The coefficients of this equation belong to sufficiently wide classes of functions which are the generalizations of Vekua classical space. The formula of the general solution and the necessary and sufficient solvability conditions of this problem are established.

We consider the impact generating triple for the following irregular Carlemann-Bers-Vekua System (see I.N. Vekua, Generalized analytic functions, Nauka, Moscow, 1988, and V. Jikia, Georgian Math. J., vol. 17, (2010)) on the classes of functions induced by irregular Carlemann-Bers-Vekua equations.
