Tsygan's generalized Gerstenhaber formality conjecture for chains
Let be an associative algebra. Write for its Hochschild cochain complex and for its Hochschild chain complex. For a Gerstenhaber algebra , let be the odd-parameter deformation defined by
Tsygan's generalized Gerstenhaber formality conjecture. For any associative algebra , the Hochschild chain complex is a module over the algebra , and its underlying -module structure over is given by the action of Hochschild cochains through the operators . If this holds, then for a smooth manifold the Hochschild chains and differential forms acquire corresponding -module structures; the source gives no resolution status.
