The set of solutions for abstract volterra equations in lp([0, a], rm)
(Elsevier BV, 1999-11-01)
Continuation fixed point theorems for locally convex linear topological spaces
(Elsevier BV, 1996-08-01)
We present continuation results for operators between locally convex linear topological spaces. These results will then be applied to obtain existence principles for differential equations on semi-infinite intervals.
Fixed-point theory for the sum of two operators
(Elsevier BV, 1996-01-01)
We extend a fixed-point theorem of Reinermann  for the sum of two operators. Our results are then used to establish new existence results for differential equations in Banach spaces.
Fixed-point theory for multivalued mappings in completely regular topological vector spaces
(Elsevier BV, 1998-11-01)
Continuation principles and d-essential maps
(Elsevier BV, 1999-12-01)
Fixed-point theory for weakly sequentially continuous mappings
(Elsevier BV, 1998-03-01)
Some fixed-point theorems are established for weakly contractive operators. These results will then be used to establish existence principles for functional, differential, and integral equations.
Fixed points for set-valued mappings in locally convex linear topological spaces
(Elsevier BV, 1998-07-01)
Weakly contractive zero epi maps
(Elsevier BV, 1999-10-01)
