Estimates and regularization for solutions of some ill-posed problems of elliptic and parabolic type
Tóm tắt
In this paper, we examine, in a systematic fashion, some ill-posed problems arising in the theory of heat conduction. In abstract terms, letH be a Hilbert space andA: D (A)⊂H→H be an unbounded normal operator, we consider the boundary value problemü(t)=Au(t), 00 is not well-posed. Suppose we are given approximationsx
