Nonlocal Conditions for Lower Semicontinuous Parabolic Inclusions

Nonlocal Conditions for Lower Semicontinuous Parabolic Inclusions

Let Ω be an open bounded domain in N , N ≥ 2, with a smooth boundary ∂Ω. We denote the norm usually the Euclidean norm of x ∈ Ω by ‖x‖. Let T be a positive real number. Set QT Ω × 0, T and ΓT ∂Ω × 0, T . For u : D → we denote its partial derivatives when they exist by ut ∂u/∂t, uxi ∂u/∂xi, uxixj ∂ u/∂xi∂xj , i, j 1, . . . ,N. Let X C QT denote the Banach space of continuous functions u : QT → ,...

Nonlocal Problems for Parabolic Inclusions

Let be a an open bounded domain in R , N 2; with a smooth boundary @ ; and T > 0. De…ne D = (0; T ) and = @ [0; T ]: In this paper we are concerned with the existence of solutions of the following parabolic inclusion ut + Lu 2 F (x; t; u), (x; t) 2 D; u(x; t) = 0; (x; t) 2 subjected to the nonlocal condition u(x; 0) = R T 0 g(x; t; u(x; t))dt for x 2 : We provide su¢ cient conditions on L; F; g...

Lower Semicontinuous Differential Inclusions with State Constrains 1

The main purpose of the present paper is to impose onesided Lipschitz condition for differential inclusions on a closed and convex domain of a uniformly convex Banach space. Both differential inclusions with almost upper demicontinuous and almost lower semicontinuous right–hand sides are considered. The existence theorems are proved and it is shown that the set of solutions is connected. AMS Ma...

Lower semicontinuous type regularity conditions for subdifferential calculus

We give a lower semicontinuous type regularity condition and a closedness type one which turn out to be necessary and sufficient for the fulfillment of two different formulae involving the εsubdifferential of a perturbation function, respectively. These regularity conditions prove to be sufficient also for having formulae for the classical subdifferential of a perturbation function. Some recent...
