The periodic problem for the second order integro-differential equations with distributed deviation
(Institute of Mathematics CAS, 2020-06-12)
In the paper we describe the classes of unique solvability of the Dirichlet and mixed two point boundary value problems for the second order linear integro-differential equation b u (t) = p0 (t)u(t) + p1 (t)u(1 (t)) + p(t, ...
The focal boundary value problem for strongly singular higher-order nonlinear functional-differential equations
(Springer Nature, 2015-01-30)
The a priori boundedness principle is proved for the two-point right-focal boundary value problems for strongly singular higher-order nonlinear functional-differential equations. Several sufficient conditions of solvability ...
Lasota–Opial type conditions for periodic problem for systems of higher-order functional differential equations
(BioMed Central, 2020-06-05)
In the paper we study the question of solvability and unique solvability of systems of the higher-order functional differential equations. In the paper in some sense optimal conditions that guarantee the unique solvability ...
