Euler Characteristics of Tautological Sheaves on Hilbert Schemes of Points
Euler Characteristics Tautological Sheaveas Hilbert Schemes of Points
2015/3/24
Professor Chern recruited geometers, physicists and combinatorists to work at Nankai Institute of Mathematics (now Chern Institute of Mathematics).
Partially balance incomplete block (PBIB) design is based on association scheme. There are many kinds of association schemes and the structure of association scheme itself is an important object in co...
On estimation of the exponentiated Pareto distribution under different sample schemes
Bayes estimators Maximum likelihood estimator
2010/9/20
Bayes and classical estimators have been obtained for two parameters aexponentiated Pareto distribution when sample is available from complete, type I and type II censoring scheme. Bayes estimators ha...

2010/9/21
This paper presents a numerical comparison of third order Lo − stable numerical schemes for the two-dimensional parabolic partial differential equations subject to nonlocal boundary conditions. ...
Fourth order positively smoothed Pade schemes for parabolic partial differential equations with nonlocal boundary conditions
Fourth order positively smoothed Pade schemes parabolic partial differential equations
2010/9/26
Parabolic partial differential equation with nonlocal boundary conditions arise in modeling of various physical phenomena in areas such as chemical diffusion, thermoelasticity, heat conduction process...
The classes of the quasihomogeneous Hilbert schemes of points on the plane

2010/11/23
In this paper we give a formula for the classes (in the Grothendieck ring of complex quasi-projective varieties) of irreducible components of $(1,k)$-quasi-homogeneous Hilbert schemes of points on th...
We describe derived moduli functors for a range of problems involving schemes and quasi-coherent sheaves, and give cohomological conditions for them to be representable by derived geometric n-stacks....
Fourth-order accurate simplified coupled characteristics-based schemes for the hyperbolic heat conduction equations
hyperbolic heat conduction equations numerical method of characteristics
2010/9/10
Roe and Arora [1] derived a fourth-order accurate coupled characteristicsbased scheme for the hyperbolic heat conduction equations (mistakenly concluding that it was only third-order accurate [2]) by ...
Characteristics-based schemes for the hyperbolic heat conduction equations
hyperbolic heat conduction equations numerical method of characteristics
2010/9/15
In [1], we derived and studied three fourth-order accurate characteristicsbased schemes with unit Courant number for the hyperbolic heat conduction equations. Herein, we extend these schemes to Couran...
Specialized hybrid Newton schemes for matrix pth roots
Specialized hybrid Newton schemes matrix pth roots
2010/9/14
We discuss different variants of Newton’s method for computing a pth root of a given matrix. A suitable implementation is presented for solving the Sylvester equation, that appears at every Newton’s i...

2008/6/26
Two iterative schemes for the solution of an H-system with Dirichlet boundary data for a revolution surface are studied: a Newton imbedding type procedure, which yields the local quadratic convergence...
