Solvability of singular dirichlet boundary-value problems with given maximal values for positive solutions
(Cambridge University Press (CUP), 2005-02-01)
The singular boundary-value problem (g(x'(t)))' = muf (t, x(t), x'(t)), x(0) = x(T) = 0 and max {x(t) : 0 less than or equal to t less than or equal to T} = A is considered. Here p is the parameter and the negative function ...
Singular positone and semipositone boundary value problems of second order delay differential equations
(Institute of Mathematics, Czech Academy of Sciences, 2005-06-01)
In this paper we present some new existence results for singular positone and semipositone boundary value problems of second order delay differential equations. Throughout our nonlinearity may be singular in its dependent ...
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 ...

Dead cores of singular dirichlet boundary value problems with ϕ-laplacian
(Institute of Mathematics, Czech Academy of Sciences, 2008-07-30)
The paper discusses the existence of positive solutions, dead core solutions and pseudodead core solutions of the singular Dirichlet problem (phi(u'))' = lambda f(t, u, u'), u(0) = u(T) = A. Here lambda is the positive ...
