Theory of ground states for classical Heisenberg spin systems I

We formulate part I of a rigorous theory of ground states for classical, finite, Heisenberg spin systems. The main result is that all ground states can be constructed from the eigenvectors of a real, symmetric matrix with entries comprising the coupl...

Waring ranks of sextic binary forms via geometric invariant theory

We determine the Waring ranks of all sextic binary forms with complex coefficients using a Geometric Invariant Theory approach. Using the five basic invariants for sextic binary forms, our results give a rapid method to determine the Waring rank of a...

L-Infinity Structures on Spaces with 3 One-Dimensional Components

L-Infinity structures have been a subject of recent interest in physics, where they occur in closed string theory and in gauge theory. This paper provides a class of easily constructible examples of $L_n$ and $L_{\infty}$ structures on graded vecto...

Matrix Realization of Gauge Theory on Discrete Group $Z_2$

We construct a $2\times 2$ matrix algebra as representation of functions on discrete group $Z_2$ and develop the gauge theory on discrete group proposed by Starz in the matrix algebra. Accordingly, we show that the non-commutative geometry model bu...

La controverse de 1874 entre Camille Jordan et Leopold Kronecker

During the whole of 1874, Camille Jordan and Leopold Kronecker quar- relled vigorously over the organisation of the theory of bilinear forms. That theory promised a "general" and "homogeneous" treatment of numerous questions arising in various 19th-c...

Internal Universes in Models of Homotopy Type Theory

We begin by recalling the essentially global character of universes in various models of homotopy type theory, which prevents a straightforward axiomatization of their properties using the internal language of the presheaf toposes from which these mo...

Analysis and theory about kafka on the shore

I have a theory that explains a lot about what’s going on in kafka on the shore and helps to uncover some of its mysteries. I’m curious about what others might think. I first read it enjoying the ...

Near-Field Channel Modeling for Electromagnetic Information Theory

Electromagnetic information theory (EIT) is one of the emerging topics for 6G communication due to its potential to reveal the performance limit of wireless communication systems. For EIT, the research foundation is reasonable and accurate channel mo...

Effective Onsite Interaction for Dynamical Mean-Field Theory

A scheme to incorporate non-local polarizations into the dynamical mean-field theory (DMFT) and a tailor-made way to determine the effective interaction for the DMFT are systematically investigated. Applying it to the two-dimensional Hubbard model, w...

Cohomology theories with supports

For $E$ a presheaf of spectra on the category of smooth $k$-schemes satisfying Nisnevich excision, we prove that the canonical map from the algebraic singular complex of the theory $E$ with quasi-finite supports to the theory $E$ with supports inters...
