Symmetric inverse semigroup
__NOTOC__
In abstract algebra, the set of all partial bijections on a set ''X'' (aka one-to-one partial transformations) forms an inverse semigroup, called the symmetric inverse semigroup (actually a monoid) on ''X''. The conventional notation for the symmetric inverse semigroup on a set ''X'' is \mathcal_X〔Hollings 2014, p. 252〕 or \mathcal_X〔Ganyushkin and Mazorchuk 2008, p. v〕 In general \mathcal_X is not commutative.
Details about the origin of the symmetric inverse semigroup are available in the discussion on the origins of the inverse semigroup.
==Finite symmetric inverse semigroups==
When ''X'' is a finite set , the inverse semigroup of one-one partial transformations is denoted by ''C''''n'' and its elements are called charts or partial symmetries.〔Lipscomb 1997, p. 1〕 The notion of chart generalizes the notion of permutation. A (famous) example of (sets of) charts are the hypomorphic mapping sets from the reconstruction conjecture in graph theory.〔Lipscomb 1997, p. xiii〕
The cycle notation of classical, group-based permutations generalizes to symmetric inverse semigroups by the addition of a notion called a ''path'', which (unlike a cycle) ends when it reaches the "undefined" element; the notation thus extended is called ''path notation''.〔Lipscomb 1997, p. xiii〕
