Banach SSD spaces and classes of monotone sets
In this paper, we unify the theory of SSD spaces and the theory of strongly
representable sets, and we apply our results to the theory of the various
classes of maximally monotone sets. In particular, we prove that type (ED),
dense type, type (D), type (NI) and strongly representable are equivalent
concepts and, consequently, that the known properties of strongly representable
sets follow from known properties of sets of type (ED).Comment: 32 page
Quadrivariate existence theorems and strong representability
In this paper, we give conditions under which we can compute the conjugate of
a convex function on the product of two Frechet spaces defined in terms of
another convex function on the product of two (possibly different) Frechet
spaces. We use this result to give simple proofs of some (both old and new)
results for Banach spaces, and deduce some (both old and new) stability results
for strongly representable multifunctions. We take as our starting point a
result on closed convex cones in the product of two Frechet spaces.Comment: 17 pages. Plain TeX (TeXshop
GOSSEZ'S SKEW LINEAR MAP AND ITS PATHOLOGICAL MAXIMALLY MONOTONE MULTIFUNCTIONS
In this note, we give a generalization of Gossez's example of a maximally
monotone multifunction such that the closure of its range is not convex, using
more elementary techniques than in Gossez's original papers. We also discuss
some new properties of Gossez's skew linear operator and its adjoint. While
most of this paper uses elementary functional analysis, we correlate our
results with those obtained by using the Stone-Cech compactification of the
integers.Comment: 8 page
