And here is the description of our book with Leonid Positselski on quadratic algebras published by the American Mathematical Society in 2005.

- Algebraic geometry of Poisson brackets, Journal of Math. Sciences 84 (1997), no.5, 1413-1444.

- Theta identities with complex multiplication, Duke Math. J. 96 (1999), 377-400.

- Perverse sheaves on a triangulated space, Math. Research Letters 4 (1997), 191-199.

- (with Daniel Spielman) Nearly-linear Size Holographic Proofs, Proceedings of the 26-th AMC Symposium on the theory of computing, 194-203 (1994).

- Polynomials on the finite plane. A note I wrote in 1993 about the same problem as the above paper with Spielman, but using more algebraic geometry.
