    On the Hochschild homology of smash biproducts
    (Elsevier B.V., 2021-02) Kaygun, Atabey; Sütlü, Serkan Selçuk
    We develop a new spectral sequence in order to calculate the Hochschild homology of smash biproducts (also called the twisted tensor products) of unital associative algebras A#B provided one of A or B has Hochschild dimension less than 2. We use this spectral sequence to calculate Hochschild homology of the algebra Mq(2) of quantum 2×2-matrices.

    Hochschild cohomology of reduced incidence algebras
    (World Scientific Publishing Co Pte Ltd, 2016-10-19) Kanuni Er, Müge; Kaygun, Atabey; Sütlü, Serkan Selçuk
    We compute the continuous Hochschild cohomology of four reduced incidence algebras: the algebra of formal power series, the algebra of exponential power series, the algebra of Eulerian power series, and the algebra of formal Dirichlet series. We achieve the result by carrying out the computation for the coalgebra Cotor-groups of their pre-dual coalgebras.
