Let K be an algebraically closed field of characteristic zero. An affine algebraic variety X over K is toral if it is isomorphic to a closed subvariety of a torus K*. We study the group Aut(X) of regular automorpshims of a toral variety X. We prove that if T is a maximal torus in Aut(X), then X is ...

The conference “Interactions between Representation Theory and Algebraic Geometry” was held at the University of Chicago on August 21–25, 2017. It brought together about 150 participants from several major universities in the USA and abroad, more than half of whom were junior mathematicians. It featured 21 talks by eminent mathematicians from the USA, Europe, and Asia on topics ...

We prove that there are no bounded domains with smooth boundaries in even-dimensional Euclidean spaces, such that the volumes cut off from them by affine hyperplanes depend algebraically on these hyperplanes. For convex ovals in R2, this is Lemma XXVIII from Newton's ‘Philosophiae naturalis principia mathematica’. ...

The workshop Tropical Aspects in Geometry, Topology and Physics was devoted to a wide discussion and exchange of ideas between the leading experts representing various points of view on the subject. The development of tropical geometry is based on deep links between problems in real and complex enumerative geometry, symplectic geometry, quantum fields theory, mirror ...

Let S be a semiabelian variety over an algebraically closed field, and let X be an irreducible subvariety not contained in a translate of a proper algebraic subgroup of S. We show that the number of irreducible components of [n]^−1 (X) is bounded uniformly in n, and moreover that the bound is uniform in families ...

We compute the center of the ring of PD differential operators on a smooth variety over $\bZ/p^n\bZ$ confirming a conjecture of Kaledin. More generally, given an associative algebra A0 over $\bF_p$ and its flat deformation An over $\bZ/p^{n+1}\bZ$ we prove that under a certain non-degeneracy condition the center of An is isomorphic to the ring ...

The Handbook of Moduli, comprising three volumes, offers a multi-faceted survey of a rapidly developing subject aimed not just at specialists but at a broad community of producers of algebraic geometry, and even at some consumers from cognate areas. The thirty-five articles in the Handbook, written by fifty leading experts, cover nearly the entire range of the field. They ...

We introduce a theory of the b-function (or Bernstein-Sato polynomial) in positive characteristic. Let be a field of characteristic and let be a nonconstant polynomial. The b-function of is an ideal of a nonnoetherian commutative algebra of characteristic but it has "roots" in. We prove the existence of the b-function as well as the rationality ...

Let M be a closed symplectic manifold of volume V. We say that M admits a full symplectic packing by balls if any collection of symplectic balls of total volume less than V admits a symplectic embedding to M. In 1994 McDuff and Polterovich proved that symplectic packings of Kahler manifolds can be characterized in ...

I prove that $\frac{2}{d}$, $\frac{2d-3}{(d-1)^2}$, $\frac{2d-1}{d(d-1)}$,
$\frac{2d-5}{d^2-3d+1}$ and $\frac{2d-3}{d(d-2)}$ are the smallest log
canonical thresholds of reduced plane curves of degree $d\geqslant 3$. I
describe reduced plane curves of degree $d$ whose log canonical thresholds are
these numbers. I prove that every reduced plane curve of degree $d\geqslant 4$
whose log canonical threshold is smaller than $\frac{5}{2d}$ is GIT-unstable

For every smooth del Pezzo surface $S$, smooth curve $C\in|-K_{S}|$ and $\beta\in(0,1]$, we compute the $\alpha$-invariant of Tian $\alpha(S,(1-\beta)C)$ and prove the existence of K\"ahler--Einstein metrics on $S$ with edge singularities along $C$ of angle $2\pi\beta$ for $\beta$ in certain interval. In particular we give lower bounds for the invariant $R(S,C)$, introduced by Donaldson as ...
