Mathematical chemistry is a branch of theoretical chemistry for discussion and prediction of the molecular structure using mathematical methods without necessarily referring to quantum mechanics. In theoretical chemistry, distance-based molecular structure descriptors are used for modeling physical, pharmacologic, biological and other properties of chemical compounds. The Wiener Polarity index ...

despite the profusion of flowers that develop on olive trees, only a few set fruit during the growing season and only about 1-2% of the fruit remains on the trees at maturity. therefore, to maximize fruit set and yield, it is important for growers to understand the cross-compatibility between cultivars when planning to establish an olive orchard. this study was carried out in shiraz, fars provi...

the present paper introduces the notion of the complete fuzzy norm on a linear space. and, some relations between the fuzzy completeness and ordinary completeness on a linear space is considered, moreover a new form of fuzzy compact spaces, namely b-compact spaces and b-closed spaces are introduced. some characterizations of their properties are obtained.
