Dreissenid mussels (the zebra mussel Dreissena polymorpha and the quagga mussel D. bugensis) are ecosystem engineers that modify the physical environment by increasing light penetration. Such aâ€¦ (More)

There is a substantial theory (modelled on permutation representations of groups) of representations of an inverse semigroup S in a symmetric inverse monoidIX , that is, a monoid of partialâ€¦ (More)

We present a method for constructing factorizable inverse monoids (FIMs) from a group and a semilattice, and show that every FIM arises in this way. We then use this structure to describe aâ€¦ (More)

The dual symmetric inverse monoid I âˆ— n is the inverse monoid of all isomorphisms between quotients of an n-set. We give a monoid presentation of I âˆ— n and, along the way, establish criteria for aâ€¦ (More)

Particulate matter with a diameter below 10â€…Âµ (PM10) has been a major concern in the Tamar Valley, Launceston, where wood heaters are extensively used. We examined the relationship betweenâ€¦ (More)

We describe GreenÂ’s relations on the partition monoid, two of its submonoids, and the related Jones and Brauer monoids. Key Words: partition monoid, Jones monoid, ideal structure 2000 Mathematicsâ€¦ (More)

Inverse semigroups generalise both groups and semilattices, and describe partial symmetries just as groups do for total symmetries; they also arise naturally in appropriately rich categories,â€¦ (More)
