    Abstract: In this work, a numerical analysis of a mathematical model for the preservation of forestry biomass is investigated. The model is divided into three compartments as density of forest biomass, density of wood based industries and density of synthetic industries. The Laplace Decomposition Method is used to obtain approximate solutions in the form of ... Show More

    Abstract: In this paper the notion of fuzzy semi-P-spaces is introduced and studied. It is established that the class of fuzzy semi-P-spaces lies between the classes of fuzzy-P-spaces and fuzzy almost-P-spaces. It is established that fuzzy fuzzy σ-nowhere dense sets in fuzzy Semi-P-spaces are fuzzy Semi-closed sets and fuzzy Gδ-sets and fuzzy Fσ-sets are fuz... Show More
