Prime component-preservingly amphicheiral link with odd minimal crossing number
component-preservingly amphicheiral link minimal crossing number Tait's conjecture
2012/3/1
For every odd integer $c\ge 21$, we raise an example of a prime component-preservingly amphicheiral link with minimal crossing number $c$.
On Virtual Crossing Numbers for Virtual Knots
Knot virtual knot graph crossing number parity
2011/9/20
Abstract: The aim of the present paper is to prove that the minimal number of virtual crossings for some families of virtual knots grows quadratically with respect to the minimal number of classical c...
Fractional relaxation equations and Brownian crossing probabilities of a random boundary
Fractional relaxation equation Generalized Mittag-Leffler functions Processes with random time
2011/9/5
Abstract: We analyze here different forms of fractional relaxation equations of order {\nu}\in(0,1) and we derive their solutions both in analytical and in probabilistic forms. In particular we show t...
Edge-Removal and Non-Crossing Perfect Matchings
Edge-Removal Non-Crossing Matchings Combinatorics Probability
2011/9/5
Abstract: We study the following problem - How many arbitrary edges can be removed from a complete geometric graph with 2n vertices such that the resulting graph always contains a perfect non-crossing...
Abstract: We prove a large deviations principle for the empirical law of the block sizes of a uniformly distributed non-crossing partition. As an application we obtain a variational formula for the ma...
Scalar Moduli, Wall Crossing and Phenomenological Predictions
Wall Crossings Intrinsic Geometry Moduli Configurations
2011/3/2
We present the scalar moduli stabilization from the perspective of the real intrinsic
geometry.
The expected value for the weighted crossing number of a randomly weighted graph is studied. A variation of the Crossing Lemma for expectations is proved. We focus on the case where the edge-weights a...
Point sets that minimize $(\le k)$-edges, $3$-decomposable drawings, and the rectilinear crossing number of $K_{30}$
k–edges 3-decomposability rectilinear crossing number
2010/12/10
There are two properties shared by all known crossing-minimizing geometric drawings of Kn, for n a multiple of 3.First, the underlying n-point set of these drawings has exactly 3k+2

The level crossing analysis of German stock market index (DAX) and daily oil price time series
German stock market index daily oil price time series
2010/4/27
The level crossing analysis of DAX and oil price time series are given. We determine the average frequency of positive-slope crossings, $\nu_{\alpha}^+$, where $T_{\alpha} =1/\nu_{\alpha}^+ $ is the a...
The Study of the Level Zero Crossing Time of a Semi-Markovian Random Walk With Delaying Screen
Semi-Markovian random walk reflecting and delaying screens
2010/3/5
In this study, a semi-Markovian random walk with delaying screen at (b > O and the first crossing time ('g1) of the zero level of this process are constructed. Furthermore, the distribution function w...
