We propose a thresholding algorithm to Willmore-type flows in $\mathbb{R}^N$. This algorithm is constructed based on the asymptotic expansion of the solution to the initial value problem for a fourth order linear parabolic partial differential equati

Consistently constrained WZWN models on G/{S x U(1)^n} is given by constraining currents of the WZWN models with G. Poisson brackets are set up on the light-like plane. Using them we show the Virasoro algebra for the energy-momentum tensor of constra

Currents of the SL(N) WZWN model are constrained so that the remaining symmetry is a symmetry of constrained currents as well. Such consistency enables us to study the Poisson structure of constrained SL(N) WZWN models properly. We establish the Pois

We consider the approximation scheme of the American call option via the discrete Morse semiflow. It is the minimizing scheme of a time-semidiscretized variational functional. In this paper we obtain a rate of convergence of approximate solutions. In

In many textbooks of statistics, we often see the central limit theorem says that if for each n∈N, Xn follows the same distribution with the mean μ and the variance σ2, then it suffices to take n≥25(or n≥5 and so on) so that the sample mean

To elucidate the grazing-induced changes in soil nutrient cycling, we compared vegetation and soil C and N dynamics, including inorganic N content and total C and N contents, among four plots: Quercus serrata plots inside and outside of a deer exclus
