investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Almost Complex Structures and Geometric Quantization

We study two quantization schemes for compact symplectic manifolds with almost complex structures. The first of these is the Spinc quantization. We prove the analog of Kodaira vanishing for the Spinc Dirac operator, which shows that the index space of this operator provides an honest (not virtual) vector space semiclassically. We also introduce a new quantization scheme, based on a rescaled Lap...

A Derived Approach to Geometric Mckay Correspondence in Dimension Three

We propose a three dimensional generalization of the geometric McKay correspondence described by Gonzales-Sprinberg and Verdier in dimension two. We work it out in detail in abelian case. More precisely, we show that the Bridgeland-King-Reid derived category equivalence induces a natural geometric correspondence between irreducible representations of G and subschemes of the exceptional set of G...

Canonical Dimension of Orthogonal Groups

We prove Berhuy-Reichstein’s conjecture on the canonical dimension of orthogonal groups showing that for any integer n ≥ 1, the canonical dimension of SO2n+1 and of SO2n+2 is equal to n(n + 1)/2. More precisely, for a given (2n + 1)-dimensional quadratic form φ defined over an arbitrary field F of characteristic 6= 2, we establish certain property of the correspondences on the orthogonal grassm...

Orthogonal complex structures on certain Riemannian 6-manifolds∗

It is shown that the Hermitian-symmetric space CP1 × CP1 × CP1 and the flag manifold F1,2 endowed with any left invariant metric admit no compatible integrable almost complex structures (even locally) different from the invariant ones. As an application it is proved that any stable harmonic immersion from F1,2 equipped with an invariant metric into an irreducible Hermitian symmetric space of co...
