In 2+1 dimensional gravity, a dreibein and the compatible spin connection can represent a space-time containing a closed spacelike surface Î£ only if the associated SO(2,1) bundle restricted to Î£ hasâ€¦ (More)

Brain extracellular fluid (ECF) concentration of YM992, a novel antidepressant, was determined using brain microdialysis to investigate the high partition of this drug to the brain after systemicâ€¦ (More)

Large-N renormalization group equations for oneand two-matrix models are derived. The exact renormalization group equation involving infinitely many induced interactions can be rewritten in a formâ€¦ (More)

The renormalization group approach is studied for large N models. The approach of BrÃ©zin and Zinn-Justin is explained and examined for matrix models. The validity of the approach is clarified byâ€¦ (More)

A Hamiltonian cycle of a graph is a closed path that visits every vertex once and only once. It serves as a model of a compact polymer on a lattice. I study the number of Hamiltonian cycles, orâ€¦ (More)

We study the susceptibility propagation, a message-passing algorithm to compute correlation functions. It is applied to constraint satisfaction problems and its accuracy is examined. As a heuristicâ€¦ (More)

We study critical and universal behaviors of unitary invariant non-gaussian random matrix ensembles within the framework of the large-N renormalization group. For a simple double-well model we findâ€¦ (More)

An exact renormalization group equation is derived for the free energy of matrix models. The renormalization group equation turns out to be nonlinear for matrix models, as opposed to linear forâ€¦ (More)

A statistical model of loops on the three-dimensional lattice is proposed and is investigated. It is O(n)-type but has loop fugacity that depends on global three-dimensional shapes of loops in aâ€¦ (More)

We summarize our renormalization group approach for the vector model as well as the matrix model which are the discretized quantum gravity in oneand two-dimensional spacetime. A difference equationâ€¦ (More)
