Tsygan's generalized Gerstenhaber formality conjecture for chains
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.
