This paper characterizes the structure and topology of simple inverse ω-semigroups with compact maximal subgroups, showing they are topologically isomorphic to specific Bruck-Reilly extensions and examining the topological implications of adjoining a zero element.
This research paper investigates the algebraic structure of OIn(L), the semigroup of finite partial order isomorphisms with rank less than or equal to n on an infinite linearly ordered set (L, ⩽), demonstrating that it is a stable, combinatorial, inverse semigroup with a tight ideal series and only admits Rees' congruences.
