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.
From applicational point of view, I am interested in the nonlinear mathematics (e.g., soliton property) in sub-atomic physics. Neutrinoless double-beta decay is also studied. This study is associated with clarifying the fundamental property of neutrinos such as Majorana or Dirac neutrino nature.

*** Publication Highlights (refereed papers: almost 50) ***
As the first author, for example, I have representative publications in the following academic journals
[Math] "Methods Funct. Anal. Topology" (2 papers) ...
[Phys] "Phys. Rev. Lett." (2 papers), "New J. Phys." (1 paper) ...
