On a group of normalized solutions of the higher-dimensional Prouhet--Tarry--Escott problem
Munenori Inagaki, Hideki Matsumura, Masanori Sawa +1
We elucidate, for the first time, a novel group-theoretic structure that arises from certain solutions of the -dimensional Prouhet--Tarry--Escott problem of degree and size…

Ellipsoidal designs and the Prouhet--Tarry--Escott problem
Hideki Matsumura, Masanori Sawa
The notion of ellipsoidal design was first introduced by Pandey (2022) as a full generalization of spherical designs on the unit circle . In this paper, we elucidate the advan…
