## On equations of Schrödinger type with generalized potential.(Russian)Zbl 0586.34003

The paper presents sufficient conditions for the existence and the uniqueness of solutions of equation (1) $$Lu(t)+Fu(t)=f(t),$$ $$t\in S$$, in a domain $$S\subseteq R^ n$$ where $$L=\sum_{k}a_ kD^ k$$ is a linear differential operator with generalized coefficients $$a_ k$$, $$L\geq 0$$ and f, F are generalized functions. F is conventionally termed the potential. Besides others it is proved that all solutions of (1) may be found as solutions of the generalized Dirichlet problem for the equation $$Lu(t)=f(t)$$.
