Real Rational Surfaces Are Quasi-Simple [PDF]

open access: yesJ. Reine Angew. Math. 551 (2002), 87--99, 2001
We show that a real rational (over $\C$) surfaces are quasi-simple, i.e., that such a surface is determined up to deformation in the class of real surfaces by the topological type of its real structure.

The Baer Radical Of Generalized Matrix Rings [PDF]

open access: yesProc. of the Sixth SIAM Conf. on Parallel Processing for Scientific Computing, pp.546--551, Norfolk, Virginia, 1993. Eds: R.F. Sincovec, D.E. Keyes, M.R. Leuze, L.R. Petzold, D.A. Reed., 2004
In this paper, we introduce a new concept of generalized matrix rings and build up the general theory of radicals for g.m.rings. Meantime, we obtain $$\bar{r}_b(A)=g.m.r_b(A)=\sum\{r_b(A_{ij})\mid i, j\in I\}=r_b(A)$$

Ideal classes of three dimensional Sklyanin algebras [PDF]

open access: yesJournal of Algebra 276 (2004) 515-551, 2005
In this paper we classify graded reflexive ideals, up to isomorphism and shift, in certain three dimensional Artin-Schelter regular algebras. This classification is similar to the classification of right ideals in the first Weyl algebra, a problem that was completely settled recently. The situation we consider is substantially more complicated however.
