Weyl invariant Dirac-Born-Infeld-Einstein theory
Nahomi Kan, Takuya Maki, Kiyoshi Shiraishi
We consider a Weyl invariant extension of Dirac-Born-Infeld type gravity. An appropriate choice of the metric hides the scalar degree of freedom which is required by the local scal…
A preliminary distance to W 75N in the Cygnus X star-forming region
K. L. J. Rygl, A. Brunthaler, K. M. Menten +6
Cygnus X is one of the closest giant molecular cloud complexes and therefore an extensively studied region of ongoing high mass star formation. However, the distance to this region…
Sharp upper bounds of the Betti numbers for a given Hilbert polynomial
Giulio Caviglia, Satoshi Murai
We show that there exists a saturated graded ideal in a standard graded polynomial ring which has the largest total Betti numbers among all saturated graded ideals for a fixed Hilb…
Face vectors of simplicial cell decompositions of manifolds
Satoshi Murai
In this paper, we study face vectors of simplicial posets that are the face posets of cell decompositions of topological manifolds without boundary. We characterize all possible fa…
Schrödinger uncertainty relation, Wigner-Yanase-Dyson skew information and metric adjusted correlation measure
Shigeru Furuichi, Kenjiro Yanagi
In this paper, we give a Schrödinger-type uncertainty relation using the Wigner-Yanase-Dyson skew information. In addition, we give Schrödinger-type uncertainty relation by use of…
What Kinds of Accretion Disks Are There in the Nuclei of Radio Galaxies?
Osamu Kaburaki, Takanobu Nankou, Naoya Tamura +1
It seems to be a widely accepted opinion that the types of accretion disks (or flows) generally realized in the nuclei of radio galaxies and in further lower mass-accretion rate nu…
