Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Computations in equivariant algebraic topology
等变 代数拓扑 计算
2023/5/17
Modern algebraic topology sees equivariance arising in unexpected context. Equivariant cohomology carries rich structures but is much harder to compute. In 2009, Hill, Hopkins, and Ravenel solved the ...

Techniques of computations of Dolbeault cohomology of solvmanifolds
Dolbeault cohomology solvmanifolds Differential Geometry
2011/9/20
Abstract: We consider semi-direct products $\C^{n}\ltimes_{\phi}N$ of Lie groups with lattices $\Gamma$ such that $N$ are nilpotent Lie groups with left-invariant complex structures. We compute the Do...
A new algebraic and arithmetic framework for interval computations
algebraic arithmetic framework interval computations Numerical Analysis
2011/10/9
Abstract: In this paper we propose some very promissing results in interval arithmetics which permit to build well-defined arithmetics including distributivity of multiplication and division according...
Finite Projective Geometry based Fast, Conflict-free Parallel Matrix Computations
Distributed Computing Parallel Algorithms Parallel Processing
2011/9/29
Abstract: Matrix computations, especially iterative PDE solving (and the sparse matrix vector multiplication subproblem within) using conjugate gradient algorithm, and LU/Cholesky decomposition for so...
Relations between $\beta$ and $\delta$ for QP and LP in Compressed Sensing Computations
Relations $\beta$ and $\delta$ QP LP Compressed Sensing Computations
2011/2/25
In many compressed sensing applications, linear programming (LP) has been used to reconstruct
a sparse signal.

We give a survey on eta invariants including methods of computation and applications in differential topology.
Homology computations for complex braid groups
Homology computations complex braid groups
2010/11/23
Complex braid groups are the natural generalizations of braid groups associated to arbitrary (finite) complex reflection groups. We investigate several methods for computing the homology of these gro...
Free energy computations by minimization of Kullback-Leibler divergence: an efficient adaptive biasing potential method for sparse representations
Free energy Kullback-Leibler divergence
2010/11/17
The present paper proposes an adaptive biasing potential for the computation of free energy landscapes. It is motivated by statistical learning arguments and unifies the tasks of biasing the molecula...
Computations in Cubic Function Fields of Characteristic Three
Computations Cubic Function Fields of Characteristic Three
2010/11/29
This paper contains an account of arbitrary cubic function fields of characteristic three. We define a standard form for an arbitrary cubic curve and consider its function field. By considering an int...
We consider the Yamabe invariant of a compact orbifold with finitely many singular points. We prove a fundamental inequality for the estimate of the invariant from above, which also includes a criteri...
What is a space? Computations in emergent algebras and the front end visual system

2010/12/13
With the help of link diagrams with decorated crossings, I explain computations in emergent algebras, introduced in [6], as the kind of com-putations done in the front end visual system.

Index computations Rabinowitz Floer homology
2010/12/9
In this note we study two index questions. In the first we establish the relationship between the Morse indices of the free time action functional and the fixed time action functional. The
second is ...

Monte Carlo matrix computations based compression
2010/9/10
Here we construct an algorithm based on the minimisation of data by using a compressed matrix for parallel matrix computations. The idea is to minimise the communication between master and slave by el...
