摘要：
Abstract: In the article, we examine well-posedness questions in the Sobolev spaces of the inversesource problem in the case of a quasilinear parabolic system of the second order. The main part ofthe operator is linear. The overdetermination conditions are values of a solution at some collectionof interior points. It is demonstrated that, in the case of at most linear growth of the nonlinearity,there exists a unique global (in time) solution and the problem is well-posed in the Sobolevclasses. The conditions on the data are minimal and the results are sharp. © 2020, Allerton Press, Inc.
