Abstract: We will introduce a new invariant of any associative DG algebra. It comes with a map to its negative cyclic homology. It is expected that this map is zero for any DG algebra over a field of characteristic zero. This vanishing would imply the Kontsevuch-Soibelman degeneration conjecture for smooth and proper DG algebras.
