Positive solutions in the sense of distributions of singular boundary value problems
(American Mathematical Society (AMS), 2008-01-01)
We obtain positive solutions in the sense of distributions of singular boundary value problems using perturbation and variational methods.
Positive solutions of singular and nonsingular fredholm integral equations

Inclusion and intersection theorems with applications in equilibrium theory in g-convex spaces
(The Korean Mathematical Society, 2010-09-01)
In this paper we obtain a very general theorem of rho-compatibility for three multivalued mappings, one of them from the class B. More exactly, we show that given a G-convex space Y, two topological spaces X and Z, a ...
Measures of noncompactness and asymptotic stability of solutions of a quadratic hammerstein integral equation
(Rocky Mountain Mathematics Consortium, 2011-12-01)
In this paper we consider the existence of asymptotically stable solutions of a quadratic Hammerstein integral equation. This equation is investigated in the space of real functions defined, bounded and continuous on the ...
Existence theorems for certain classes of singular boundary value problems

Existence theory for nonresonant singular boundary value problems
(Cambridge University Press (CUP), 1995-10-01)
We present some existence results for the ''nonresonant'' singular boundary value problem 1/pq(py')'+ mu y = f(t, y) a.e. on [0,1] with lim(t-->0) + p(t)y'(t)=y(1)=0. Here mu is such that 1/pq(pu')'+mu u=0 a.e. on [0,1] ...
Resonant singular boundary value problems
(Rocky Mountain Mathematics Consortium, 1995-12-01)
Existence theory is developed for the ''resonant'' singular problem (1/(pq))(py')' + lambda(0)y = f(t,y,py') almost everywhere on [0, 1] with lim(t-->0+) p(t)y'(t) = ay(1) + blim(t-->1-) p(t)y'(t) = 0. Here lambda(0) ...
Existence results for differential equations with reflection of the argument
(Cambridge University Press (CUP), 1994-10-01)
Existence principles are given for systems of differential equations with reflection of the argument. These are derived using fixed point analysis, specifically the Nonlinear Alternative. Then existence results are deduced ...
