Sufficient conditions of solvability and unique solvability of the boundary value problem
are established, where
are measurable functions and the vector function
is measurable in the first and continuous in the last kmn arguments; moreover, this function may have nonintegrable singularities with respect to the first argument. 相似文献

Based on the coincidence degree theory of Mawhin, we get a new general existence result for the following higher-order multi-point
boundary value problem at resonance
