Abstract: The talk will be on the algebraic structure present in both parts of the
title.  This algebraic story is most pronounced for E2-algebras in the category of
2-vector spaces (also known as braided fusion categories).  Condensation gives rise to
an equivalence relation on such E2-algebras (Witt equivalence) with sets of equivalence
classes exhibiting nice properties, e.g.  being abelian groups (Witt groups).  The Witt
group of braided fusion categories is a countably generated abelian group with the
torsion part annihilated by 32.
