Complex saddles of three-dimensional de Sitter gravity via holography
Heng-Yu Chen, Yasuaki Hikida, Yusuke Taki +1
We determine complex saddles of three-dimensional gravity with a positive cosmological constant by applying the recently proposed holography. It is sometimes useful to consider a c…
The lifespan estimates of classical solutions of one dimensional semilinear wave equations with characteristic weights
Shunsuke Kitamura, Hiroyuki Takamura, Kyouhei Wakasa
In this paper, we study the lifespan estimates of classical solutions for semilinear wave equations with characteristic weights and compactly supported data in one space dimension.…
Small data blow-up for the wave equation with a time-dependent scale invariant damping and a cubic convolution for slowly decaying initial data
Masahiro Ikeda, Tomoyuki Tanaka, Kyouhei Wakasa
In the present paper, we study the Cauchy problem for the wave equation with a time-dependent scale invariant damping, i.e. and a cubic convolution $(|x|…
Finite time blowup of solutions to semilinear wave equation in an exterior domain
Motohiro Sobajima, Kyouhei Wakasa
We consider the initial-boundary value problem of semilinear wave equation with nonlinearity in exterior domain in . Especially, the lifespan of b…
Multiloop Amplitudes of Light-cone Gauge NSR String Field Theory in Noncritical Dimensions
Nobuyuki Ishibashi, Koichi Murakami
Feynman amplitudes of light-cone gauge superstring field theory are ill-defined because of various divergences. In a previous paper, one of the authors showed that taking the world…
Gauge covariant solution for the Schwinger-Dyson equation in three-dimensional QED with Chern-Simons term
Yuichi Hoshino, Tomohiro Inagaki, Yuichi Mizutani
An Abelian gauge theory with Chern-Simons term is investigated for a four-component Dirac fermion in 1+2 dimensions. The Ball-Chiu (BC) vertex function is employed to modify the ra…
