A homology plane of general type can have at most a cyclic quotient singularity
R. V. Gurjar, M. Koras, M. Miyanishi +1
We show that a homology plane of general type has at worst a single cyclic quotient singular point. An example of such a surface with a singular point does exist. We also show that…
Vortex flow for a holographic superconductor
Kengo Maeda, Takashi Okamura
We investigate energy dissipation associated with the motion of the scalar condensate in a holographic superconductor model constructed from the charged scalar field coupled to the…
Non-minimally coupled hybrid inflation
Seoktae Koh, Masato Minamitsuji
We discuss the hybrid inflation model where the inflaton field is nonminimally coupled to gravity. In the Jordan frame, the potential contains term as well as terms in the or…
Cosmological intersecting brane solutions
Masato Minamitsuji, Nobuyoshi Ohta, Kunihito Uzawa
The recent discovery of an explicit dynamical description of p-branes makes it possible to investigate the existence of intersection of such objects. We generalize the solutions de…
Dynamical p-branes with a cosmological constant
Kei-ichi Maeda, Masato Minamitsuji, Nobuyoshi Ohta +1
We present a class of dynamical solutions in a D-dimensional gravitational theory coupled to a dilaton, a form field strength, and a cosmological constant. We find that for any D d…
On two pieces of folklore in the AdS/CFT duality
Kengo Maeda, Makoto Natsuume, Takashi Okamura
In the AdS/CFT duality, it is often said that a local symmetry in a bulk theory corresponds to a global symmetry in the corresponding boundary theory, but the global symmetry can b…
