Study of Certain Topics in Fuzzy Supra Topological Space

Molla, Md. Yahia (Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh, 2013-07)

American Mathematician Lotfi A. Zadeh in 1965 first introduced the concept of fuzzy set. He interpreted a fuzzy set on a set as a mapping from the set into the unit interval I= [0, 1], which is a generalization of the ...
Study of Principal n-ideals of a Lattice

Azad, Md. Abul Kalam (Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh, 2006-07)

This thesis studies extensively the Principal n-ideals of a lattice. The idea of n-ideals in a lattice was first introduced by Cornish and Noor in studying the kernels around a particular element n, of a skeletal congruence ...
A study on 0-distributive nearlattice

Rahman, Md. Zaidur (Khulna University of Engineering & Technology (KUET), Khulna, Bangladesh, 2014-11)

In this thesis study of the nature of the 0-distributive nearlattices is presented. By a nearlattice S we will always mean a meet semilattice together with the property that any two elements possessing a common upper bound, ...
