Koszul spaces
Koszul spaces Algebraic Topology
2011/8/25
Abstract: We prove that a nilpotent space is both formal and coformal if and only if it is rationally homotopy equivalent to the derived spatial realization of a graded commutative Koszul algebra. We ...
Generalized Lantern Relations and Planar Line Arrangements
Generalized Lantern Relations Planar Line Arrangements Geometric Topology
2011/8/24
Abstract: In this paper we show that to each planar line arrangement defined over the real numbers, for which no two lines are parallel, one can write down a corresponding relation on Dehn twists that...
Exceptional surgeries on components of two-bridge links
Dehn surgery, exceptional surgery, 2-bridge link
2011/8/24
Abstract: In this paper, we give a complete classification of exceptional Dehn surgeries on a component of a hyperbolic two-bridge link in the 3-sphere.
Hyperbolicity and identification of Berge knots of types VII and VIII
doubly primitive knot Alexander polynomial Reidemeister torsion
2011/8/23
Abstract: T. Saito and M. Teragaito asked in their paper whether Berge knots of type VII, which can be situated on the fiber surface of the lefthand trefoil, are hyperbolic, and showed that some infin...
Amphicheiral links with special properties, II
amphicheiral link Jones polynomial HOMFLY polynomial Alexander polynomial
2011/8/23
Abstract: We determine prime amphicheiral links with at least 2 components and up to 11 crossings. There are 27 such links. We check also special amphicheiralities. Most of prime links with up to 11 c...
Amphicheiral links with special properties, I
algebraically split link amphicheiral link invertible link Alexander polynomial Reidemeister torsion
2011/8/23
Abstract: We provide necessary conditions for the Alexander polynomials of algebraically split component-preservingly amphicheiral links. We raise a conjecture that the Alexander polynomial of an alge...
On $L^p$ inequality for differential forms and $L^p$ cohomology of a semialgebraic set for $p>>1$
differential forms semialgebraic set Geometric Topology
2011/8/23
Abstract: We study Poincar\'e type $L^p$ inequality on a compact semialgebraic subset of $\R^n$ for $p>>1$. First we derive a local inequality by using a Lipschitz deformation retraction with estimate...
Topological classification of zero-dimensional $M_\omega$-groups
Topological classification zero-dimensional
2010/11/23
A topological group $G$ is called an $M_\omega$-group if it admits a countable cover $\K$ by closed metrizable subspaces of $G$ such that a subset $U$ of $G$ is open in $G$ if and only if $U\cap K$ i...

On the topology of free paratopological groups
Paratopological group free paratopological group
2010/12/1
The result often known as Joiner’s lemma is funda-mental in understanding the topology of the free topological group F(X) on a Tychonoff space X.
Half-balanced braided monoidal categories and Teichmueller groupoids in genus zero
Half-balanced braided monoidal categories Teichmueller groupoids in genus zero
2010/12/6
We introduce the notions of a half-balanced braided monoidal category and of its contraction. These notions give rise to an explicit description of the action of the Galois group of Q on Teichm¨uller ...
Dynamic Adaptive Mesh Refinement for Topology Optimization
Dynamic Adaptive Mesh Refinement Topology Optimization
2010/12/13
We present an improved method for topology optimization with both adaptive mesh refinement and
derefinement. Since the total volume fraction in topology optimization is usually modest, after a few in...
得到局部$G$-凸一致空间上具有$S$-KKM性质的集值映射的新的几乎不动点定理和不动点定理.我们的结果对已有文献中的相应结论进行了改进和一般化.
A new technique is proposed for the analysis of shape optimization problems. The technique uses the asymptotic analysis of boundary value problems in singularly perturbed geometrical domains. The asym...
