On the Cyclicity of the Unramified Iwasawa Modules of the Maximal Multiple -Extensions Over Imaginary Quadratic Fields
Takashi Miura, Kazuaki Murakami, Keiji Okano +1
For an odd prime number , we study the number of generators of the unramified Iwasawa modules of the maximal multiple -extensions over Iwasawa algebra. In a previo…
Galois coinvariants of the unramified Iwasawa modules of multiple -extensions
Takashi Miura, Kazuaki Murakami, Rei Otsuki +1
For a CM-field and an odd prime number , let be a certain multiple -extension of . In this paper, we study several basic properties of the u…
Dynamical generation of fermion mass hierarchy in an extra dimension
Yukihiro Fujimoto, Takashi Miura, Kenji Nishiwaki +1
We propose a new mechanism to produce a fermion mass hierarchy dynamically in a model with a singlet generation of fermions. A five dimensional gauge theory on an interval with poi…
Classification of three-generation models on magnetized orbifolds
Tomo-hiro Abe, Yukihiro Fujimoto, Tatsuo Kobayashi +4
We classify the combinations of parameters which lead three generations of quarks and leptons in the framework of magnetized twisted orbifolds on , , an…
Chromo-Natural Inflation in the Axiverse
Ippei Obata, Takashi Miura, Jiro Soda
We study chromo-natural inflation in the axiverse. More precisely, we investigate natural inflation with two axions coupled with a SU(2) gauge field. Assuming a hierarchy between t…
Operator analysis of physical states on magnetized orbifolds
Tomo-hiro Abe, Yukihiro Fujimoto, Tatsuo Kobayashi +3
We discuss an effective way for analyzing the system on the magnetized twisted orbifolds in operator formalism, especially in the complicated cases , and…
