Mathematics of Multisets

  title={Mathematics of Multisets},
  author={Apostolos Syropoulos},
This paper is an attempt to summarize most things that are related to multiset theory. We begin by describing multisets and the operations between them. Then we present hybrid sets and their operations. We continue with a categorical approach to multisets. Next, we present fuzzy multisets and their operations. Finally, we present partially ordered multisets.
