Matrix generators for Weil representations

Mikko Korhonen

Let $r$ be an odd prime and $F$ a field containing a primitive $r$ th root of unity. Then for all $ℓ \geq 1$ , there is a faithful representation $f: \operatorname{Sp}_{2…

Symmetries for the 4HDM. II. Extensions by rephasing groups

Jiazhen Shao, Igor P. Ivanov, Mikko Korhonen

We continue classification of finite groups which can be used as symmetry group of the scalar sector of the four-Higgs-doublet model (4HDM). Our objective is to systematically cons…

Orthogonal irreducible representations of finite solvable groups in odd dimension

Mikko Korhonen

We prove that if $G$ is a finite irreducible solvable subgroup of an orthogonal group $O (V, Q)$ with $dim V$ odd, then $G$ preserves an orthogonal decomposition of $V$ into $1$ -spa…
