Abstract

We prove the existence and uniqueness of solutions to inverse problems for third-order equations with the pointwise overdetermination. The unknowns are a solution to the equation and two or three external sources. [ABSTRACT FROM AUTHOR]

Abstract

In this paper, we consider a nonlocal parabolic equation associated with initial and Dirichlet boundary conditions. First, we discuss the vacuum isolating behavior of solutions with the help of a family of potential wells. Then we obtain a threshold of global existence and blow up for solutions with critical initial energy. Furthermore, for those solutions that satisfy J(u0) ≤ d and I(u0) ≠ 0, we show that global solutions decay to zero exponentially as time tends to infinity and the norm of blow-up solutions increases exponentially.

3. A version of biting lemma for unbounded sequences in LE1 with applications.

Author

Florescu, Liviu C. and Godet-Thobie, Christiane

Subjects
*STOCHASTIC convergence, *PARABOLIC differential equations, *PARTIAL differential equations, *HEAT equation, *MATHEMATICAL physics, *MATHEMATICAL analysis
Abstract

The aim of the present work is to introduce the notion of finite tightness and then to obtain some results of compactness in the lack of L1 — boundedness. We use these results in order to obtain information about the limit of the solutions for a sequence of one dimensional heat equations. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
