组合数学和代数编码讲座—— Covers of the Integers by Residue Classes and their Extensions to Groups

报告人：孙智伟教授（南京大学）报告时间：2024年10月18日周五下午3:00-4:00报告地点：海纳苑2幢820摘要：A system A={a_s+n_sZ: s=1,2,...,k} of k residue classes is called a cover of Z if any integer belongs to one of the k residue classes. This concept was introduced by P. Erdos in the 1950s. Erdos ever conjectured that A is a cover of Z whenever it covers 1,...,2^k. In this talk we introduce s...

组合数学和代数编码讲座—— Decoding algorithm of twisted GRS codes and twisted Goppa codes

报告人：岳勤教授报告时间：2024年10月18日周五下午2:00-3:00报告地点：海纳苑2幢820摘要： In this talk, we use extended Euclid's algorithm to support new decoding algorithms for two classes of maximum distance separable (MDS) twisted generalized Reed-Solomon (TGRS) codes of parameters [n, n-t, t+1 ] over F_q. For t even, they can correct t/2 errors with time complexity O(qn). Moreover, we...

A simple quadrature method for singular integral operators on surfaces

报告人: Bowei Wu (吴博尉)时间：2024年8月8日上午10:00地点：海纳苑2幢820摘要: Boundary Value Problems (BVPs) are ubiquitous in scientific and engineering applications. The Boundary Integral Equation Method is a robust and accurate method for solving BVPs, which has the great advantage of dimensionality reduction: all of the unknowns reside on the boundary surface instead of in its enclosing volume. ...
