Constructing Quantum Network Coding Schemes from Classical Nonlinear Protocols
Quantum Network Coding Schemes Classical Nonlinear Protocols
2011/3/3
The k-pair problem in network coding theory asks to send k messages simultaneously between k
source-target pairs over a directed acyclic graph. In a previous paper [ICALP 2009, Part I, pages 622–633]...
For m 2 N,m 1, we determine the irreducible components of the m − th jet scheme of a toric
surface S. For m big enough, we connect the number of a class of these irreducible components to the...
Deformations of modules of maximal grade and the Hilbert scheme at determinantal schemes
Deformations of modules of maximal grade Hilbert scheme determinantal schemes

Let R be a polynomial ring and M a finitely generated graded R-module of maximal grade (which means that the ideal It(A) generated by the maximal minors of a homogeneous presentation matrix.
Optimal error bounds for two-grid schemes applied to the Navier-Stokes equations
two-grid schemes the Navier-Stokes equations
2010/11/18
We consider two-grid mixed-finite element schemes for the spatial discretization of the incompressible Navier-Stokes equations. A standard mixed-finite element method is applied over the coarse grid ...
A Semigroup Point Of View On Splitting Schemes For Stochastic (Partial) Differential Equations
Semigroup Point Splitting Schemes Differential Equations
2010/11/18
We construct normed spaces of real-valued functions with controlled growth on possibly infinite-dimensional state spaces such that semigroups of positive, bounded operators $(P_t)_{t\ge 0}$ thereon w...
Plane wave stability of some conservative schemes for the cubic Schrödinger equation
Plane wave conservative schemes the cubic Schrö dinger equation
2010/11/11
The plane wave stability properties of the conservative schemes of Besse and Fei et al. for the cubic Schr\"{o}dinger equation are analysed. Although the two methods possess many of the same conserva...
Leaves and trajectories for schemes. Application to the comparison of three classical sheaves over the differential spectrum
Leaves trajectories schemes classical sheaves the differential spectrum
2010/11/15
We define leaves and trajectories for schemes endowed with a vector field. With the help of these tools, we are able to give a geometrical interpretation and to generalize several results and constru...
Optimized IR-HARQ Schemes Based on Punctured LDPC Codes over the BEC
Optimized IR-HARQ Schemes Based Punctured LDPC Codes BEC
2010/12/6
We study incremental redundancy hybrid ARQ (IR-HARQ) schemes based on punctured, finite-length, LDPC codes. The transmission is assumed to take place over time varying binary erasure channels, such as...
We construct and analyze a family of semi-discretized difference
schemes with two parameters for the Korteweg-de Vries (KdV) equation.
The scheme possesses the first four near-conserved quantities f...
3D HYBRID DEPTH MIGRATION AND FOUR-WAY SPLITTING SCHEMES
3D depth migration Multiway splitting Data line Wavefield computation Finite-difference Hybrid method
2007/12/12
The alternately directional implicit (ADI) scheme is usually
used in 3D depth migration. It
splits the 3D square-root operator along crossline and inline
directions alternately.
In this paper, bas...
The boundary value problem for the nonlinear parabolic system is
solved by the finite difference method with nonuniform meshes. The existence
and a priori estemates of the discrete vector solutions ...
