For a finite undirected graph G = (V, E) and a subset A βŠ† V , the vertex switching of G by A is defined as the graph G A = (V, E ), which is obtained from G by removing all edges between A and its complement A and adding as edges all nonedges between A and A. The switching class [G] determined by G

We prove that a Tate construction A u1; : : : ; un | @(ui) = zi over a di erential graded algebra A, on cycles z1; : : : ; zn in A β‰₯1 , is acyclic if and only if the map of graded-commutative algebras H0(A)[y1; : : : ; yn] β†’ H(A), with yi β†’ cls(zi), is an isomorphism.
