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 ...

Stress tensor computations at Mount St. Helens (1995-1998)
Mount St. Helens (USA) fault-plane solutions inversion stress field
2015/9/29
Fault plane solutions of 459 events occurring between 1995 and 1998 at Mount St. Helens (State of Washington, Northwest U.S.A.) were considered in order to infer the state of stress beneath the volcan...

de Finetti Priors using Markov chain Monte Carlo computations。
University of Queensland (UQ) scientists have made a fundamental breakthrough into how the brain decodes the visual world.
Interpretation of percolation in terms of infinity computations
Interpretation of percolation terms of infinity computations General Physics
2012/5/28
In this paper, a number of traditional models related to the percolation theory has been considered by means of new computational methodology that does not use Cantor's ideas and describes infinite an...
Assignment of resonances in dissociative recombination of HD+ ions: high-resolution measurements compared with accurate computations
Assignment of resonances dissociative recombination high-resolution measurements accurate computations
2011/8/11
Abstract: The collision-energy resolved rate coefficient for dissociative recombination of HD+ ions in the vibrational ground state is measured using the photocathode electron target at the heavy-ion ...

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...

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...
Numerical Computations of Conductivities over Agglomerated Continuum Percolation Models

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...
Predicting Zonal Flows -- A Comprehensive Reynolds-Stress Response-Functional from First-Principles-Plasma-Turbulence Computations
Reynolds-Stress First-Principles-Plasma-Turbulence
2011/8/31
Turbulence driven zonal flows play an important role in fusion devices since they improve plasma confinement by limiting the level of anomalous transport. Current theories mostly focus on flow excitat...
