Taijie You · Journal of Southwest China Normal University · 2011
Let Xn={1,2,…,n} be a natural order set,let POn and PODn be the semigroups consisting of partial order-preserving transformations and the partial order-preserving or order-reserving transformations on Xn,respectively.In this paper,the authors describe the maximal regular subsemisemigoup of ideals of PODn,and obtain their classification completely.
