Inequality in resource allocation and population dynamics models
Masahiro Anazawa
The Hassell model has been widely used as a general discrete-time population dynamics model that describes both contest and scramble intraspecific competition through a tunable exp…
Combined effect of successive competition periods on population dynamics
Masahiro Anazawa
This study investigates the effect of competition between individuals on population dynamics when they compete for different resources during different seasons or during different…
Fractal Structure with a Typical Scale
Masahiro Anazawa, Atushi Ishikawa, Tadao Suzuki +1
In order to understand characteristics common to distributions which have both fractal and non-fractal scale regions in a unified framework, we introduce a concept of typical scale…
Geometrical Construction of Heterogeneous Loop Amplitudes in 2D Gravity
Masahiro Anazawa, Atushi Ishikawa
We study a disk amplitude which has a complicated heterogeneous matter configuration on the boundary in a system of the (3,4) conformal matter coupled to two-dimensional gravity. I…
Splitting of Heterogeneous Boundaries in a System of the Tricritical Ising Model Coupled to 2-Dim Gravity
Masahiro Anazawa, Atushi Ishikawa
We study disk amplitudes whose boundaries have heterogeneous matter states in a system of conformal matter coupled to 2-dim gravity. They are analysed by using the 3-matrix…
D0-branes in an H-field Background and Noncommutative Geometry
Masahiro Anazawa
It is known that if we compactify D0-branes on a torus with constant B-field, the resulting theory becomes SYM theory on a noncommutative dual torus. We discuss the extension to th…
