Second Workshop on Numerical Algebra, Algorithms and Analysis

in Honor of Professor Ken Hayami's Retirement

This workshop is dedicated to Professor Ken Hayami on the occasion of his retirement. He will be retiring in March 2021 as a faculty member at the National Institute of Informatics and The Graduate University for Advanced Studies (SOKENDAI). All interested in numerical algebra, analysis, and algorithms are welcome to participate in this workshop.
