Instanton counting with a surface operator and the chain-saw quiver
Hiroaki Kanno, Yuji Tachikawa
We describe the moduli space of SU(N) instantons in the presence of a general surface operator of type N=n_1+ ... +n_M in terms of the representations of the so-called chain-saw qu…

Time-dependent matter instability and star singularity in gravity
Kazuharu Bamba, Shin'ichi Nojiri, Sergei D. Odintsov
We investigate a curvature singularity appearing in the star collapse process in gravity. In particular, we propose an understanding of the mechanism to produce the curvatur…

On Isotropic Turbulence in the Dark Fluid Universe
Iver Brevik, Olesya Gorbunova, Shin'ichi Nojiri +1
As first part of this work, experimental information about the decay of isotropic turbulence in ordinary hydrodynamics, u^2(t) proportional to t^{-6/5}, is used as input in FRW equ…
