Resolutions of toric subvarieties by line bundles and applications

A Hanlon, J Hicks, O Lazarev - Forum of Mathematics, Pi, 2024 - cambridge.org
Given any toric subvariety Y of a smooth toric variety X of codimension k, we construct a
length k resolution of under the map of toric Frobenius. The resolutions are built from a …

Computational tools for cohomology of toric varieties

R Blumenhagen, B Jurke, T Rahn - Advances in High Energy …, 2011 - Wiley Online Library
Novel nonstandard techniques for the computation of cohomology classes on toric varieties
are summarized. After an introduction of the basic definitions and properties of toric …

A short resolution of the diagonal for smooth projective toric varieties of Picard rank 2

MK Brown, M Sayrafi - Algebra & Number Theory, 2024 - msp.org
Given a smooth projective toric variety X of Picard rank 2, we resolve the diagonal sheaf on
X× X by a linear complex of length dim⁡ X consisting of finite direct sums of line bundles. As …

Exceptional sequences of invertible sheaves on rational surfaces

L Hille, M Perling - Compositio Mathematica, 2011 - cambridge.org
In this article we consider exceptional sequences of invertible sheaves on smooth complete
rational surfaces. We show that to every such sequence one can associate a smooth …

Homological mirror symmetry for Milnor fibers via moduli of A∞ A_∞‐structures

Y Lekili, K Ueda - Journal of Topology, 2022 - Wiley Online Library
We show that the base spaces of the semiuniversal unfoldings of some weighted
homogeneous singularities can be identified with moduli spaces of A∞ A_∞‐structures on …

Tate resolutions on toric varieties

MK Brown, D Erman - Journal of the European Mathematical Society, 2024 - ems.press
We develop an analogue of Eisenbud–Fløystad–Schreyer's Tate resolutions for toric
varieties. Our construction, which is given by a noncommutative analogue of a Fourier …

Monodromy of monomially admissible Fukaya-Seidel categories mirror to toric varieties

A Hanlon - Advances in Mathematics, 2019 - Elsevier
Mirror symmetry for a toric variety involves Laurent polynomials whose symplectic topology
is related to the algebraic geometry of the toric variety. We show that there is a monodromy …

The special McKay correspondence and exceptional collections

A Ishii, K Ueda - Tohoku Mathematical Journal, Second Series, 2015 - jstage.jst.go.jp
We show that the derived category of coherent sheaves on the quotient stack of the affine
plane by a finite small subgroup of the general linear group is obtained from the derived …

Maximal lengths of exceptional collections of line bundles

AI Efimov - Journal of the London Mathematical Society, 2014 - academic.oup.com
In this paper, we construct infinitely many examples of toric Fano varieties with Picard
number three, which do not admit full exceptional collections of line bundles. In particular …
