  • Kim, Hee Sik; Neggers, J.; So, Keum Sook (2016)
    In this paper, we introduce fuzzy rank functions for groupoids, and we investigate their roles in the semigroup of binary systems by using the notions of right parallelisms and ρ-shrinking groupoids.
  • Kim, Heek Sik; Neggers, J.; So, Keum Sook (2013)
    In this paper, we introduce the notion of generalized Fibonacci sequences over a groupoid and discuss it in particular for the case where the groupoid contains idempotents and pre-idempotents. Using the notion of ...
  • Allen, P.J.; Kim, Hee Sik; Neggers, J. (2016)
    In this paper, we introduce the concept of several types of groupoids related to semigroups, viz., twisted semigroups for which twisted versions of the associative law hold. Thus, if (X, ∗) is a groupoid and if ϕ : X2 → ...
