Quadratic-Defect Completions of Spherical -Design Orbits

Kuan-Cheng Chien, Ming-Hsuan Kang

We study how spherical -designs arising from finite group orbits can be completed to spherical -designs by adjoining further orbits, allowing weights in the general theory. F…

Ramanujan Cayley Graphs with Normal Connection Sets in Ratio-One Frobenius Groups

Ming-Hsuan Kang, Chi-Jung Yang

Let be a finite Frobenius group with and . We classify all Ramanujan Cayley graphs of whose connection sets are normal, in the sense of being un…

A solution to Butler's positivity conjecture

Peter L. Guo, Mingyang Kang, Rui Xiong

Let be distinct partitions such that and . We prove Butler's positivity conjecture posed in 1994: the expansion of the Macdonald intersecti…

Zeta functions of over non-Archimedean local fields

Ming-Hsuan Kang, Jiu-Kang Yu

Let be the Bruhat--Tits building of , where is a non-Archimedean local field. We introduce geometric -geodesics in by means of…

A Lam--Postnikov--Pylyavskyy inequality for hybrid Grothendieck polynomials

Peter L. Guo, Mingyang Kang, Jiaji Liu

We prove a multivariate Lam--Postnikov--Pylyavskyy type inequality for hybrid Grothendieck polynomials, unifying and refining results for stable and dual stable Grothendieck polyno…

Spherical 2-Designs from Finite Group Orbits

Kuan-Cheng Chien, Ming-Hsuan Kang

We classify all spherical 2-designs that arise as orbits of finite group actions on real inner product spaces. Although it is well known that such designs can occur in representati…
