Fixed-point theory for the sum of two operators
(Elsevier BV, 1996-01-01)
We extend a fixed-point theorem of Reinermann [1] for the sum of two operators. Our results are then used to establish new existence results for differential equations in Banach spaces.
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.
