Closure Operations on Subgroups
… mathematicians have conducted research involving closure operations on the ideals of commutative rings. The most accessible paper on this is written by Neil Epstein, entitled "A Guide to Closure Operations in Commutative Algebra". This paper compiles much of the research done on the topic, and …

Algebraic study of fuzzy finite switchboard automata
… subsystems. The newly defined Kuratowski fuzzy closure operation is used to establish fuzzy topology on a GFSA. Semigroup actions are closely related to automata. By extending the algebraic properties of GFSA, the General Fuzzy Switchboard Transformation Semigroup (GFSTS) has been introduced and …

Standard Closure Operations on Several Rings of Dimension One
… the cardinality of the set of star and semistar operations on a domain R. However the cardinality of the set of such operations has only just begun to be examined in the non-domain setting. Epstein has shown a correspondence between the set of finite-type semistar operations of a ring and the …

Temporal and Spatial Analysis of Landfills and Transfer Stations in Saskatchewan
… regression analysis was conducted, and landfill closure operation showed no obvious correlation to division land area, annual budget, or population density. Rural division 18, representing Northern Saskatchewan, was identified as one of the challenging areas. Inclusion of division 18 in data …
