													Abstract | 
												 
												
													| 
													 | 
												 
												
													| In this article we study the (finite-type, cl-closed) closure operations on ideals of a BCK-algebra,
with an emphasis on structural properties. Also we give several theorems that make different closure
operations, especially on a quotient and Noetherian BCK-algebra. In particular, we show that the
intersection and union (by imposing some additional conditions) of closure operations is a closure
operation and every closure operation is a finite type on any finitely generated ideal. Moreover by
given the notions of residuated quotient ideals and the meet of two ideals, we conclude some related
results. |
