Lazard-style CAD and Equational Constraints
James H. Davenport, Akshar S. Nair, Gregory K. Sankaran +1
McCallum-style Cylindrical Algebra Decomposition (CAD) is a major improvement on the original Collins version, and has had many subsequent advances, notably for total or partial eq…
Slopes of Siegel cusp forms and geometry of compactified Kuga varieties
Flora Poon, Riccardo Salvati Manni, Gregory Sankaran
We study the Kodaira dimension of the compactified n-fold Kuga variety over the moduli space of principally polarised abelian g-folds. We construct a suitable compactification, whi…
A supersingular coincidence
G. K. Sankaran
The fifteen supersingular primes, see https://oeis.org/A002267, appear in the theory of the moduli of abelian surfaces. This short expository note explains why.
Blowups with log canonical singularities
G. K. Sankaran, Francisco Santos
We show that the minimum weight of a weighted blow-up of with -log canonical singularities is bounded by a constant depending only on and…
Regular cylindrical algebraic decomposition
J. H. Davenport, A. F. Locatelli, G. K. Sankaran
We show that a strong well-based cylindrical algebraic decomposition P of a bounded semi-algebraic set is a regular cell decomposition, in any dimension and independently of the me…
Moduli of K3 Surfaces and Irreducible Symplectic Manifolds
V. Gritsenko, K. Hulek, G. K. Sankaran
The name "K3 surfaces" was coined by A. Weil in 1957 when he formulated a research programme for these surfaces and their moduli. Since then, irreducible holomorphic symplectic man…
