| Popis | We study boundary value problems with measure data in smooth bounded domains Omega, for semilinear equations. Specifically we consider problems of the form - L(V)u + f (u) = tau in Omega and tr(V)u = nu on partial derivative Omega, where L-V = Delta + V, f. is an element of C(R) is monotone increasingwith f (0) = 0 and tr V u denotes themeasure boundary trace of u associated with L-V. The potential V is an element of C-1(Omega) typically blows up at a set F subset of partial derivative Omega as dist (x, F)(-2). In general the above boundary value problem may not have a solution. We are interested in questions related to the concept of 'reduced measures', introduced in Brezis et al. (Ann Math Stud 163:55-109, 20072007) for V = 0. Our results extend results of [4] and Brezis and Ponce (J Funct Anal 229(1):95-120, 2005) and apply to a larger class of nonlinear terms f. In the case of signed measures, some of the present results are new even for V = 0. |
