Yoritaka Iwata Last updated: Dec 2, 2019 at 10:30
Profile My primary interest is the operator theory in association with the operator algebra. There are some papers treating the fundamental property of infinitesimal generators, groups, and semigroups. Much attention is paid to the commutation and the nonlinearity. Its relation to abstract evolution equations is studied.
