Lattice sums of -Bessel functions, theta functions, linear codes and heat equations

Takehiro Hasegawa, Hayato Saigo, Seiken Saito +1

We extend a certain type of identities on sums of -Bessel functions on lattices, previously given by G. Chinta, J. Jorgenson, A. Karlsson and M. Neuhauser. Moreover we prove tha…

Conserved relativistic Ertel's current generating the vortical and thermodynamic aspects of spacetime

Hirofumi Sakuma, Izumi Ojima, Hayato Saigo +1

Motivated by Aoki et al.'s recent research on conserved charges and entropy current, we investigated the conservation of relativistic Ertel's current, which has received little att…

Entangled N-photon states for fair and optimal social decision making

Nicolas Chauvet, Guillaume Bachelier, Serge Huant +3

Situations involving competition for resources among entities can be modeled by the competitive multi-armed bandit (CMAB) problem, which relates to social issues such as maximizing…

Meanings, Metaphors, and Morphisms: Theory of Indeterminate Natural Transformation (TINT)

Miho Fuyama, Hayato Saigo

In the present paper, we propose a new theory named "Theory of indeterminate natural transformation (TINT)" to investigate the dynamical creation of meanings as association relatio…

Who has seen a free photon?

Izumi Ojima, Hayato Saigo

While the notion of the position of photons is indispensable in the quantum optical situations, it has been known in mathematical physics that any position operator cannot be defin…
