Hochschild cohomology of truncated quiver algebras
Yunge Xu, Yang Han, Wenfeng Jiang
For a truncated quiver algebra over a field of arbitrary characteristic, its Hochschild cohomology is calculated. Moreover, it is shown that its Hochschild cohomology algebra is fi…
Sonochemical effects on single-bubble sonoluminescence
Li Yuan
A refined hydrochemical model for single-bubble sonoluminescence (SBSL) is presented. The processes of water vapor evaporation and condensation, mass diffusion, and chemical reacti…
Symplectic Graphs and Their Automorphisms
Zhongming Tang, Zhe-xian Wan
A new family of strongly regular graphs, called the general symplectic graphs , associated with nonsingular alternate matrices is introduced. Their parameters as strongl…
A Matrix Approach to the Rational Invariants of Certain Classical Groups over Finite Fields of Characteristic Two
Zhongming Tang, Zhe-xian Wan
Let be a finite field of characteristic two and a rational function field. We use matrix methods to obtain explicit transcendental base…
Representations of Centrally-Extended Lie Algebras over Differential Operators and Vertex Algebras
Xiaoping Xu
We construct irreducible modules of centrally-extended classical Lie algebras over left ideals of the algebra of differential operators on the circle, through certain irreducible m…
Hochschild (co)homology dimension
Yang Han
In 1989 Happel conjectured that for a finite-dimensional algebra over an algebraically closed field , $\gl A< \infty$ if and only if $\hch A < \infty$. Recently Buchweitz-Gr…
