Hochschild cohomology of certain Koszul Sullivan Extensions

Research output: Contribution to journalArticlepeer-review


We consider a totally non cohomologous to zero fibration (Figure presented.), where B is an elliptic 2-stage Postnikov tower and (Figure presented.) a Koszul Sullivan model of p. In this paper, we show that the induced map in Hochschild cohomology HH*(f): HH*(∧V; ∧V) → HH*(∧V; C) is injective.
