Operations on Closure Operators

1995
Despite the powerful continuity condition, the notion of closure operator is very general. It is therefore important to provide tools for improving a given operator. Fortunately, there is a natural lattice structure for closure operators that allows us to distinguish between properties stable under meet (idempotency, hereditariness, productivity), and ...

Connectedness with Respect to a Closure Operator

Applied Categorical Structures, 2001
For categories \(\mathcal C\) that are supplied with a factorization structure \(({\mathcal E}, M)\) for sinks, a closure operator \(C\) and a subclass \(N\) of \(M\), the author introduces a concept of connected objects. He demonstrates that under suitable additional conditions on \(\mathcal C\) many classical results about topological connectedness ...

FUZZIFYING CLOSURE SYSTEMS AND CLOSURE OPERATORS

2011
In this paper, we propose the concepts of fuzzifying closure systems and Birkhoff fuzzifying closure operators. In the framework of fuzzifying mathematics, we find that there still exists a one to one correspondence between fuzzifying closure systems and Birkhoff fuzzifying closure operators as in the case of classical mathematics.

Operative Nuances of Myelomeningocele Closure

Neurosurgery, 2002
ALTHOUGH ADVANCES IN prenatal care and diagnosis have reduced the incidence of spina bifida, repair of neural tube defects remains one of the standard cases encountered by pediatric neurosurgeons. The operative techniques used in closure of these congenital defects have remained essentially unchanged during the past 2 decades; however, the operative ...
