Positive and maximal positive solutions of singular mixed boundary value problem
(Walter de Gruyter GmbH, 2009-01-01)
The paper is concerned with existence results for positive solutions and maximal positive solutions of singular mixed boundary value problems. Nonlinearities h(t;x;y) in differential equations admit a time singularity at ...
