A Multiplicity Fixed Point Theorem in Fréchet SpacesDonal O'Regan (1) National University of Ireland, Galway, Ireland
A new multiplicity result is presented for maps between Fréchet spaces. Our argument relies on fixed point results in Banach spaces together with a result on hemicompact maps. An application is also given to illustrate how the theory can be applied in practice.
Keywords: Fixed point theory, multiplicity results
