Notes on very ample vector bundles on 3 - folds
Let E be a very ample vector bundle of rank two on a smooth complex projective threefold X. An inequality about the third Segre class of E is provided when KX+detE is nef but not big, and when a suitable positive multiple of KX+det E defines a morphism X → B with connected fibers onto a smooth projective curve B, where KX is the canonical bundle of X. As an application, the case where the genus...
متن کاملHiggs branch localization of N = 1 theories on S 3 × S 1
We apply the method of Higgs branch localization to the N = 1 supersymmetric partition function on S3 × S1. As a result, we show that it can be written as the product of an elliptic vortex and anti-vortex partition function summed over a finite number of Higgs vacua.
متن کاملNotes on supersymmetric Sp(N) theories with an antisymmetric tensor
We study supersymmetric Sp(N) gauge theories with an antisymmetric tensor and degree n+1 tree level superpotential. The generalized Konishi anomaly equations derived in hep-th/0304119 and hep-th/0304138 are used to compute the low energy superpotential of the theory. This is done by imposing a certain integrality condition on the periods of a meromorphic one form. Explicit computations for Sp(2...
متن کاملOn Kummer 3-folds
We investigate a generalization of Kummer construction, as introduced in [AW08]. The aim of this work is to classify 3-dimensional Kummer varieties by computing their Poincaré polynomials.
متن کاملUpdate on 3-folds
The familiar division of compact Riemann surfaces into 3 cases g = 0, g = 1 and g ≥ 2 corresponds to the well known trichotomy of spherical, Euclidean and hyperbolic non-Euclidean plane geometry. Classification aims to treat all projective algebraic varieties in terms of this trichotomy; the model is Castelnuovo and Enriques’ treatment of surfaces around 1900 (reworked by Kodaira in the 1960s)....
