In this paper we obtain a new strong type of Steckin inequality for the linear combinations of Bernstein-Kantorovich operators,which gives the optimal appro
The main purpose of this talk is the construction and investigation of properties of the Green function for a large class of parabolic integro-differential
We establish a theorem on the existence of the solutions of the exterior Dirichlet problem for Hessian equations with prescribed asymptotic behavior at infi
