Title:  Infinitesimal bases and transitive representations of inverse
Every group is isomorphic to a group of permutations of a suitable
set. Groups form a subclass of the class of inverse semigroups, the
most important class of semigroups besides groups. 
Not every inverse semigroup is isomorphic to a transitive inverse
semigroup of partial one-to-one transformations of a set. The problem
of describing those inverse semigroups that admit such an isomorphism
was raised in 1952.  The speaker presents a new solution to this
