The upper triangular algebra loop of degree 4
(Commentationes Mathematicae Universitatis Carolinae, 2014)A natural loop structure is defined on the set U4 of unimodular uppertriangular matrices over a given field. Inner mappings of the loop are computed. It is shown that the loop is non-associative and nilpotent, of class ... -
THE NUMBER OF DISTINCT FUZZY SUBGROUPS OF THE GROUP r p q Z n × Z m × Z FOR DISTINCT PRIMES p, q, r AND + m, n ∈ Z
(Advances in Fuzzy Sets and Systems, 2022-04)The equivalence relation ‘~’ defined by Murali and Makamba is used to find the number of the distinct fuzzy subgroups of the group where p, q, r are distinct primes with m and n as positive integers. Using the criss-cut ... -
COMPUTING FUZZY SUBGROUPS OF SOME SPECIAL CYCLIC GROUPS
(Communications of the Korean Mathematical Society, 2019)In this paper, we discuss the number of distinct fuzzy subgroups of the group Zpn × Zqm × Zr, m = 1, 2, 3 where p, q, r are distinct primes for any n ∈ Z + using the criss-cut method that was proposed by Murali and ... -
