To day at the Institute seminar the senior research associate of “Diferensial Equations” Department, doctor of math. sci. Bahram Aliyev gave a talk on “Solvability of elliptic boundary value problems for operator-differential equations of second order with a spectral parameter and with the operator in the boundary conditions”.
At the paper investigated the solvability of elliptic differential operator equations with a spectral parameter and a linear operator in the boundary conditions. Obtained coercive and noncoercive estimates for solution.
