Binomial convolution sum of divisor functions associated with Dirichlet character modulo 8

Autor: Jin Seokho, Park Ho

Publikováno v: Open Mathematics, Vol 22, Iss 1, Pp 256-152 (2024)

In this article, we compute binomial convolution sums of divisor functions associated with the Dirichlet character modulo 8, which is the remaining primitive Dirichlet character modulo powers of 2 yet to be considered. To do this, we provide an expli

The multinomial convolution sum of a generalized divisor function

Autor: Park Ho

Publikováno v: Open Mathematics, Vol 20, Iss 1, Pp 419-430 (2022)

The main theorem of this article is to evaluate and express the multinomial convolution sum of the divisor function σr♯(n;N/4,N){\sigma }_{r}^{\sharp }\left(n;\hspace{0.33em}N\hspace{-0.08em}\text{/}\hspace{-0.08em}4,N) in as a simple form as poss

Machine Learning Assisted Design and Optimization of Transition Metal-Incorporated Carbon Quantum Dot Catalysts for Hydrogen Evolution Reaction

Autor: Nguyen, Duong Nguyen, Kim, Min-Cheol, Baeck, Unbeom, Lim, Jaehyoung, Shin, Namsoo, Kim, Jaekook, Choi, Heechae, Park, Ho Seok, Sim, Uk, Kim, Jung Kyu

Development of cost-effective hydrogen evolution reaction (HER) catalysts with outstanding catalytic activity, replacing cost-prohibitive noble metal-based catalysts, is critical for practical green hydrogen production. A popular strategy for promoti
