Duality and quasi-normability for complexity spaces

S Romaguera, MP Schellekens - Applied General Topology, 2002 - polipapers.upv.es
The complexity (quasi-metric) space was introduced in [23] to study complexity analysis of
programs. Recently, it was introduced in [22] the dual complexity (quasi-metric) space, as a …

Weightable quasi-metric semigroups and semilattices

S Romaguera, M Schellekens - Electronic Notes in Theoretical Computer …, 2001 - Elsevier
In [Sch00] a bijection has been established, for the case of semilattices, between invariant
partial metrics and semivaluations. Semivaluations are a natural generalization of valuations …

FIXED POINT THEOREMS FOR SET-VALUED MAPS IN QUASI-METRIC SPACES

SH Cho - Journal of the Chungcheong Mathematical Society, 2010 - jcmssubmit.ccms.or.kr
In this paper, we introduce the concept of generalized weak contractivity for set-valued maps
defined on quasi metric spaces. We analyze the existence of fixed points for generalized …
