Finite-difference zeta readout of one-loop operator spectra
Keisuke Okamura
For a positive elliptic operator , the logarithmic zeta determinant combines UV information encoded by local heat-kernel coefficients with finite contr…
Fractional stochastic model of citation dynamics with memory and volatility
Keisuke Okamura
Understanding the statistical laws governing citation dynamics remains a fundamental challenge in network theory and the science of science. Citation networks typically exhibit in-…
On the -generalised multinomial/divergence correspondence
Keisuke Okamura
The asymptotic correspondence between the probability mass function of the -deformed multinomial distribution and the -generalised Kullback-Leibler divergence, also known as…
Emergent family of Tsallis entropies from the -deformed combinatorics
Keisuke Okamura
We revisit the derivation of a formula for the -generalised multinomial coefficient rooted in the -deformed algebra, a foundational framework in the study of nonextensive sta…
