On equivariant homeomorphisms of boundaries of CAT(0) groups and Coxeter groups
Tetsuya Hosaka
In this paper, we investigate an equivariant homeomorphism of the boundaries and of two proper CAT(0) spaces and on which a CAT(0) group acts…
Algebraic study on Cameron-Walker graphs
Takayuki Hibi, Akihiro Higashitani, Kyouko Kimura +1
Let be a finite simple graph on and the edge ideal of , where is the polynomial ring over a field . Let denote…
Velocity-Field Theory, Boltzmann's Transport Equation and Geometry
Shoichi Ichinose
Boltzmann equation describes the time development of the velocity distribution in the continuum fluid matter. We formulate the equation using the field theory where the {\it veloci…
New Approach to Cosmological Fluctuation using the Background Field Method and CMB Power Spectrum
Shoichi Ichinose
A new field theory formulation is presented for the analysis of the CMB power spectrum distribution in the cosmology. The background-field formalism is fully used. Stimulated by th…
Analytical solution of stochastic model of risk-spreading with global coupling
Satoru Morita, Jin Yoshimura
We study a stochastic matrix model to understand the mechanics of risk-spreading (or bet-hedging) by dispersion. Such model has been mostly dealt numerically except for well-mixed…
Non-vanishing of Betti numbers of edge ideals and complete bipartite subgraphs
Kyouko Kimura
Given a finite simple graph one can associate the edge ideal. In this paper we prove that a graded Betti number of the edge ideal does not vanish if the original graph contains a s…
Renormalization Group Approach to Dissipative System
Shoichi Ichinose
In order to understand the dynamical mechanism of the friction phenomena, we heavily rely on the numerical analysis using various methods: molecular dynamics, Langevin equation, la…
Variational Formulation of the Log-Aesthetic Surface and Development of Discrete Surface Filters
K. T. Miura, R. Shirahata, S. Agari +2
The log-aesthetic curves include the logarithmic (equiangular) spiral, clothoid, and involute curves. Although most of them are expressed only by an integral form of the tangent ve…
Velocity-Field Theory, Boltzmann's Transport Equation, Geometry and Emergent Time
Shoichi Ichinose
Boltzmann equation describes the time development of the velocity distribution in the continuum fluid matter. We formulate the equation using the field theory where the {\it veloci…
