On generalized Kummer of rank 3 vector bundles over a genus 2 curve

open access: yesLe Matematiche, 2003
Let X be a smooth projective complex curve and let U_X (r, d) be the moduli space of semi-stable vector bundles of rank r and degree d on X (see [8]).

Non-Lorentzian M5-brane theories from holography

open access: yesJournal of High Energy Physics, 2019
M-theory on AdS 7 × S 4 admits a description where the AdS 7 factor is constructed as a timelike Hopf fibration over a non-compact three dimensional complex projective space ℂℙ ˜ 3 $$ {\tilde{\mathrm{\mathbb{CP}}}}^3 $$ [1].

Braid groups in complex projective spaces [PDF]

open access: yesarXiv, 2010
We describe the fundamental groups of ordered and unordered k point sets in complex projective space of dimension n generating a projective subspace of dimension i. We apply these to study connectivity of more complicated configurations of points.

Complex Hadamard Matrices contained in a Bose–Mesner algebra

open access: yesSpecial Matrices, 2015
Acomplex Hadamard matrix is a square matrix H with complex entries of absolute value 1 satisfying HH* = nI, where * stands for the Hermitian transpose and I is the identity matrix of order n.

An explicit expression of generating function for one-loop tensor reduction

open access: yesJournal of High Energy Physics
This work introduces an explicit expression for the generating function for the reduction of an n-gon to an (n – k)-gon. A novel recursive relation of generating function is formulated based on Feynman Parametrization in projective space, involving a ...

Continuation of CR-Automorphisms of Levi Degenerate Hyperquadrics to the Projective Space [PDF]

open access: yesarXiv, 2009
We show that every CR-automorphism of the closure of a Levi degenerate hyperquadric in the projective space extends to a holomorphic automorphism of the projective space.

Purity and hybridness of two tensors on a real hypersurface in complex projective space

open access: yesOpen Mathematics
On a real hypersurface MM in complex projective space, we can define two tensor fields of type (1, 2), AF(k){A}_{F}^{\left(k)} and AT(k){A}_{T}^{\left(k)}, associated with the shape operator AA of the real hypersurface, for any nonnull real number kk ...

A Classification of Compact Cohomogeneity One Locally Conformal Kähler Manifolds

open access: yesMathematics
In this paper, we apply a result of the classification of a compact cohomogeneity one Riemannian manifold with a compact Lie group G to obtain a classification of compact cohomogeneity one locally conformal Kähler manifolds.
