The study of Kirchhoff type equations, a nonlocal extension of classical partial differential equations, has gained considerable momentum in recent years. These equations incorporate integral ...
The Tricomi equation can be expressed in symmetric positive form. Admissible boundary conditions assure existence and uniqueness of solutions. In this paper it is shown what boundary conditions are ...
The minimal positive solutions of the heat equation on X × (-∞, T) are determined for X a homogeneous Riemannian space. A simple proof of uniqueness for the positive Cauchy problem on a homogeneous ...
