K-theoretic exceptional collections at roots of unity
Alexander Polishchuk
Using cyclotomic specializations of the equivariant -theory with respect to a torus action we derive congruences for discrete invariants of exceptional objects in derived catego…
Derivations of an effective divisor on the complex projective line
Max Wakefield, Sergey Yuzvinsky
In this paper we consider an effective divisor on the complex projective line and associate with it the module D consisting of all the derivations such that $θ(I_i)\subset I_i^…
Lie symmetries of the Chow group of a Jacobian and the tautological subring
Alexander Polishchuk
Let be the Jacobian of a smooth projective curve. We define a natural action of the Lie algebra of polynomial Hamiltonian vector fields on the plane, vanishing at the origin, o…
Universal algebraic equivalences between tautological cycles on Jacobians of curves
Alexander Polishchuk
We present a collection of algebraic equivalences between tautological cycles on the Jacobian of a curve, i.e., cycles in the subring of the Chow ring of generated by the c…
Extensions of homogeneous coordinate rings to -algebras
Alexander Polishchuk
We study -structures extending the natural algebra structure on the cohomology of , where is a very ample line bundle on a projective -dimensional…
