Nonlocal multi-point in time Cauchy problem for parabolic equations with degeneration
(Science and Education a New Dimension. Natural and Technical Sciences, 2020)
A multi-point in time problem for a parabolic equation with power singularities of arbitrary order in coefficients for time and spatial variables is considered. The existence and uniqueness of the solutions of the problem ...
Optimal control in the boundary value problem for elliptic equations with degeneration
(Matematychni Studii, 2023)
The problem of optimal control of the system described by the oblique derivative problem for the elliptic equation of the second order is studied. Cases of internal and boundary management are considered. The quality ...
