Ultra-Weak Time Operators of Schroedinger Operators
Asao Arai, Fumio Hiroshima
In an abstract framework, a new concept on time operator, ultra-weak time operator, is introduced, which is a concept weaker than that of weak time operator. Theorems on the existe…

Mathematical Analysis of a Generalized Chiral Quark Soliton Model
Asao Arai
A generalized version of the so-called chiral quark soliton model (CQSM) in nuclear physics is introduced. The Hamiltonian of the generalized CQSM is given by a Dirac type operator…

Regularities of ground states of quantum field models
Asao Arai, Masao Hirokawa, Fumio Hiroshima
Regularities and higher order regularities of ground states of quantum field models are investigated through the fact that asymptotic annihilation operators vanish ground states. M…
