Nonlocal Problem Multipoint in Time for the Evolutionary Equations with Pseudo-Bessel Operators with Variable Symbols
Ukr. Mat. Zh. - 2014. - 66, № 2. - pp. 159–175
We study the properties of the fundamental solution of a nonlocal problem multipoint in time for the evolutionary equations with pseudo-Bessel operators constructed on variable symbols. The solvability of this problem is proved in the class of bounded continuous functions even on ℝ. The integral representation of solutions is established.
Correct Solvability of a Nonlocal Multipoint (in Time) Problem for One Class of Evolutionary Equations
Ukr. Mat. Zh. - 2013. - 65, № 3. - pp. 339-353
We study properties of a fundamental solution of a nonlocal multipoint (with respect to time) problem for evolution equations with pseudo-Bessel operators constructed on the basis of constant symbols. The correct solvability of this problem in the class of generalized functions of distribution type is proved.
