Prelegent: FRANCESCO D'ANDREA
It is well known that a "bad" quotient space can be studied by associating to it the groupoid C*-algebra of its defining equivalence relation. A similar procedure for relations that are reflexive and symmetric but fail to be transitive leads to non-associative algebras. In this talk, I will discuss some properties of this procedure. (Based on a recent joint work with G. Landi and F. Lizzi.)
