On holomorphic flows on Stein surfaces: transversality, dicriticalness and stability
T. Ito, B. Scardua, Y. Yamagishi
We study the classification of the pairs where is a Stein surface and is a complete holomorphic vector field with isolated singularities on . We describe the…
Topos Quantum Theory on Quantization-Induced Sheaves
Kunji Nakayama
In this paper, we construct a sheaf-based topos quantum theory. It is well known that a topos quantum theory can be constructed on the topos of presheaves on the category of commut…
When does "Time" become "Observable" ?
Tadashi Fujimoto
We investigate some spectral properties of time operators which are obtained through Canonical Commutation Relation (CCR) and Positive Operator Valued Measure (POVM) of quantum phy…

Toshihiko Matsuki
Let be the split orthogonal group of degree over an arbitrary field of . In this paper, we classify multiple flag varieties $G/…
