Separation with restricted families of sets

Degrees of M-fuzzy families of independent L-fuzzy sets

The present paper studies fuzzy matroids in view of degree. First wegeneralize the notion of $(L,M)$-fuzzy independent structure byintroducing the degree of $M$-fuzzy family of independent $L$-fuzzysets with respect to a mapping from $L^X$ to $M$. Such kind ofdegrees is proved to satisfy some axioms similar to those satisfiedby $(L,M)$-fuzzy independent structure. ...

Some separation axioms via modified θ-open sets

Generated topology on infinite sets by ultrafilters

Let $X$ be an infinite set, equipped with a topology $tau$. In this paper we studied the relationship between $tau$, and ultrafilters on $X$. We can discovered, among other thing, some relations of the Robinson's compactness theorem, continuity and the separation axioms. It is important also, aspects of communication between mathematical concepts.

The effect of training on public participation in the in-house separation of urban wastes

Recycling and reuse of municipal solid waste is one of the most important components of waste management. In this regards, education plays an important role in people motivation and changing their behavior. The aim of this study was to identify effect of education on people participation in source separation of municipal solid waste in district 5 of Tehran municipality. In this experimental st...
