Polyakov loop extended NJL model with imaginary chemical potential
Yuji Sakai, Kouji Kashiwa, Hiroaki Kouno +1
The Polyakov loop extended Nambu--Jona-Lasinio (PNJL) model with imaginary chemical potential is studied. The model possesses the extended symmetry that QCD does.…
Hysteretic ac loss of polygonally arranged superconducting strips carrying ac transport current
Yasunori Mawatari, Kazuhiro Kajikawa
The hysteretic ac loss of a current-carrying conductor in which multiple superconducting strips are polygonally arranged around a cylindrical former is theoretically investigated a…
Application of a curvature adjusted method in image segmentation
M. Benes, M. Kimura, P. Paus +3
This article deals with flow of plane curves driven by the curvature and external force. We make use of such a geometric flow for the purpose of image segmentation. A parametric mo…
Signed-eliminable graphs and free multiplicities on the braid arrangement
Takuro Abe, Koji Nuida, Yasuhide Numata
We define specific multiplicities on the braid arrangement by using edge-bicolored graphs. To consider their freeness, we introduce the notion of bicolor-eliminable graphs as a gen…
On Lusternik-Schnirelmann category of SO(10)
Norio Iwase, Kai Kikuchi, Toshiyuki Miyauchi
Let be a compact connected Lie group and be a principal G-bundle with a characteristic map , where for some . Let $\{K_{i}{\to} F_{i-…
Charged lepton and down-type quark masses in SU(1,1) model and the structure of higgs sector
Kenzo Inoue, Naoki Yamatsu
The simplest noncompact group SU(1,1),when introduced as a symmetry group of the generations of quarks and leptons in the framework of a vector-like theory, gives an excellent view…
