Hochschild and cyclic (co)homology of superadditive categories
Deke Zhao
We define the Hochschild and cyclic (co)homology groups for superadditive categories and show that these (co)homology groups are graded Morita invariants. We also show that the Hoc…

Fusion procedure for Degenerate cyclotomic Hecke algebras
Deke Zhao, Yanbo Li
The primitive idempotents of the generic degenerate cycloctomic Hecke algebras are derived by consecutive evaluations of a certain rational function. This rational function depends…

Smoothed analysis of componentwise condition numbers for sparse matrices
Dennis Cheung, Felipe Cucker
We perform a smoothed analysis of the componentwise condition numbers for determinant computation, matrix inversion, and linear equations solving for sparse n times n matrices. The…
