Systems of Inclusions Involving Fredholm Operators and Noncompact Maps
Bollettino della Unione matematica italiana, Série 8, 10B (2007) no. 1, pp. 119-158
We consider the existence of solutions to the system of two inclusions involving Fredholm operators of nonnegative index and the so-called fundamentally restrictible maps with not necessarily convex values. We apply the technique of a solution map and, since the assumptions admit a 'dimension defect', we use the coincidence index, i.e. the homotopy invariant based on the cohomotopy theory. Two examples of applications to boundary value problems are included.
