Hochschild and cyclic (co)homology of preprojective algebras of quivers of type T
Ching-Hwa Eu
We calculate the additive and multiplicative structure (together with the grading) of the Hochschild homology and cohomology and the cyclic homology of preprojective algebras of ty…
Calabi-Yau Frobenius algebras
Ching-Hwa Eu, Travis Schedler
We define Calabi-Yau and periodic Frobenius algebras over arbitrary base commutative rings. We define a Hochschild analogue of Tate cohomology, and show that the "stable Hochschild…
The calculus structure of the Hochschild homology/cohomology of preprojective algebras of Dynkin quivers
Ching-Hwa Eu
The Hochschild homology/cohomology an associative algebra, together with the Connes differential, the contraction map and the Lie derivative, forms the structure of calculus. In th…
The product in the Hochschild cohomology ring of preprojective algebras of Dynkin quivers
Ching-Hwa Eu
In this paper, we compute the product structure of the Hochschild cohomology of preprojective algebras of quivers of type D and E over a field of characteristic zero.
Hochschild and cyclic homology of preprojective algebras of ADE quivers
Pavel Etingof, Ching-Hwa Eu
We calculate the additive structure (together with the grading) of the Hochschild homology and cohomology and the cyclic homology of preprojective algebras of types ADE.
Hochschild and cyclic homology of central extensions of preprojective algebras of ADE quivers
Ching-Hwa Eu
Let A be the central extension of the preprojective algebra of an ADE quiver introduced by P. Etingof and E. Rains in math/0503393. The paper math/0606403 computes the structure of…
