On equations containing derivative of the delta-function
The expression u′′ + aδ′u, which is consisted derivative of delta-function as a coefficient, is a formal expression and doesnʼt define operator in L2(R), because a product δ′u is not defined. So according to these reasons the study investigated the family of operators, which are approximated by the...
