Point configurations, Cremona transformations and the elliptic difference Painlevé equation
K. Kajiwara, T. Masuda, M. Noumi +2
A theoretical foundation for a generalization of the elliptic difference Painlevé equation to higher dimensions is provided in the framework of birational Weyl group action on the…
Lower bounds for Morse index of constant mean curvature tori
Wayne Rossman
We give three lower bounds for the Morse index of a constant mean curvature torus in Euclidean 3-space in terms of its spectral genus g. The first two lower bounds grow linearly in…
Toda equation and special polynomials associated with the Garnier system
Teruhisa Tsuda
We prove that a certain sequence of tau functions of the Garnier system satisfies Toda equation. We construct a class of algebraic solutions of the system by the use of Toda equati…
Carrier-Induced Magnetic Circular Dichloism in the Magnetoresistive Pyrochlore Tl2Mn2O7
H. Okamura, T. Koretsune, S. Kimura +4
Infrared magnetic circular dichloism (MCD), or equivalently magneto-optical Kerr effect, has been measured on the Tl2Mn2O7 pyrochlore, which is well known for exhibiting a large ma…
An Abductive Framework For Computing Knowledge Base Updates
Chiaki Sakama, Katsumi Inoue
This paper introduces an abductive framework for updating knowledge bases represented by extended disjunctive programs. We first provide a simple transformation from abductive prog…
Tensor Product Variational Formulation for Quantum Systems
Y. Nishio, N. Maeshima, A. Gendiar +1
We consider a variational problem for the two-dimensional (2D) Heisenberg and XY models, using a trial state which is constructed as a 2D product of local weights. Variational ener…
