Leibniz rule and exact supersymmetry on lattice: a case of supersymmetrical quantum mechanics
Mitsuhiro Kato, Makoto Sakamoto, Hiroto So
We propose a new formulation of lattice theory. It is given by a matrix form and suitable for satisfying Leibniz rule on lattice. The theory may be interpreted as a multi-flavor sy…
Instanton counting on blowup. II. -theoretic partition function
Hiraku Nakajima, Kota Yoshioka
We study Nekrasov's deformed partition function of 5-dimensional supersymmetric Yang-Mills theory compactified on a circle. Mathematically it is the generating function of the char…
Splitting criterion for reflexive sheaves
Takuro Abe, Masahiko Yoshinaga
The purpose of this paper is to study the structure of reflexive sheaves over projective spaces through hyperplane sections. We give a criterion for a reflexive sheaf to split into…
Absolute Values of Neutrino Masses implied by the Seesaw Mechanism
H. Tsujimoto
It is found that the seesaw mechanism not only explain the smallness of neutrino masses but also account for the large mixing angles simultaneously, even if the unification of the…
