CORRECT NICOLETTI PROBLEMS FOR SOME CLASSES OF PARTIAL DIFFERENTIAL EQUATIONS OF SECOND ORDER IN TIME
摘要
Nicoletti problems for a partial differential equation of second order in time, whose kernel is trivial, have been studied. The class of quasipolynomials was singled out as a class of unique solvability of the problem, and the differential-symbol method of constructing solutions was indicated. The possibility of finding solutions to problems in the classes of continuously differentiable functions was studied.
