Nino Partsvania ON TWO-POINT BOUNDARY VALUE PROBLEMS FOR TWO-DIMENSIONAL LINEAR DIFFERENTIAL SYSTEMS WITH SINGULAR COEFFICIENTS
Two-point boundary value problems for two-dimensional systems of linear differential equations with singular coefficients are considered. The cases are optimally described when the above-mentioned problems have the Fredholm property, and unimprovable in a certain sense conditions are established guaranteeing the unique solvability of those problems. îâäæñéâ. àŽêýæèñèæŽ ëîûâîðæèëãŽêæ ïŽïŽäôãîë Ž...
متن کاملThe Dirichlet and Focal Boundary Value Problems for Higher Order Quasi-halflinear Singular Differential Equations
For higher order quasi-halflinear singular differential equations, the Dirichlet and focal boundary value problems are considered. Analogues of the Fredholm first theorem are proved and on the basis of these results optimal in some sense sufficient conditions of solvability of the above-mentioned problems are found. îâäæñéâ. éŽôŽèæ îæàæï çãŽäæ êŽýâãîŽáûîòæãæ ïæêàñèŽîñèæ áæòâîâêùæŽèñîæ àŽêðëèâIJ...
