结构拓扑 拓扑优化
2016/7/19
结构是指由梁、板、壳、三维实体等组成的能够承受和传递外荷载的系统。结构拓扑是指构成结构的材料在空间中的分布方式以及构件之间的连接方式。结构拓扑优化旨在满足使用材料体积、结构承载能力、刚度指标等约束条件的前提下,寻求具有某种最优性能的结构拓扑形式。在强劲的需求推动下,结构拓扑优化成为了近三十年来计算力学领域的一个研究热点,为工程界实现轻量化以及创新设计提供了有力工具。目前结构拓扑优化的理论、方法研究...

STANDARD CONJECTURES FOR THE ARITHMETIC GRASSMANNIAN G(2; N) AND RACAH POLYNOMIALS
STANDARD CONJECTURES RACAH POLYNOMIALS
2015/12/17
We prove the arithmetic Hodge index and hard Lefschetz conjectures for the Grassmannian G = G(2; N) parametrizing
lines in projective space, for the natural arithmetic Lefschetz operator dened via t...

The orientation preserving topological symmetry group of
a graph embedded in the 3-sphere is the subgroup of the automorphism
group of the graph consisting of those automorphisms which can be
induc...
COHOMOLOGY OF U(2,1) REPRESENTATION VARIETIES OF SURFACE GROUPS
U(2,1) REPRESENTATION VARIETIES SURFACE GROUPS
2015/12/17
In this paper we use the Morse theory of the Yang-Mills-Higgs functional on the singular space of Higgs bundles on Riemann surfaces to compute the equivariant cohomology of the space of semistable U(2...
We use Young’s raising operators to give short and uniform proofs
of several well known results about Schur polynomials and symmetric functions, starting from the Jacobi-Trudi identity.
TOPOLOGICAL SYMMETRY GROUPS OF GRAPHS IN 3-MANIFOLDS
GRAPHS IN 3-MANIFOLDS SYMMETRY GROUPS
2015/12/17
We prove that for every closed, connected, orientable, irreducible 3-manifold, there exists an alternating group An which is not
the topological symmetry group of any graph embedded in the manifold.

The Ptolemy variety for SL(2; C) is an invariant of a topological ideal triangulation
of a compact 3-manifold M. It is closely related to Thurston’s gluing equation variety. The
Ptolemy variety maps...
A Hybrid Variational Front Tracking-Level Set Mesh Generator For Problems Exhibiting Large Deformations and Topological Changes
Front Tracking Arbitrary-Lagrangian-Eulerian Mesh Method
2015/12/11
We present a method for generating 2-D unstructured triangular meshes that undergo large deformations and
topological changes in an automatic way. We employ a method for detecting when topological ch...
