Ultrafast melting and recovery of collective order in the excitonic insulator Ta $_{2}$ NiSe $_{5}$

Hope M. Bretscher, Paolo Andrich, Prachi Telang +4

The layered chalcogenide Ta $_{2}$ NiSe $_{5}$ has been proposed to host an excitonic condensate in its ground state, a phase that could offer a unique platform to study and manipulat…

Branching rules and commuting probabilities for Triangular and Unitriangular matrices

Dilpreet Kaur, Uday Bhaskar Sharma, Anupam Singh

This paper concerns the enumeration of simultaneous conjugacy classes of $k$ -tuples of commuting matrices in the upper triangular group $G T_{n} (F_{q})$ and unitriangular group…

Asymptotics of the powers in finite reductive groups

Amit Kulshrestha, Rijubrata Kundu, Anupam Singh

Let $G$ be a connected reductive group defined over $F_{q}$ . Fix an integer $M \geq 2$ , and consider the power map $x \mapsto x^{M}$ on $G$ . We denote the image of $G(\mathbb F_q…

z-classes in groups: a survey

Sushil Bhunia, Anupam Singh

This survey article explores the notion of z-classes in groups. The concept introduced here is related to the notion of orbit types in transformation groups, and types or genus in…

Algorithms in Linear Algebraic Groups

Sushil Bhunia, Ayan Mahalanobis, Pralhad Shinde +1

This paper presents some algorithms in linear algebraic groups. These algorithms solve the word problem and compute the spinor norm for orthogonal groups. This gives us an algorith…

Finiteness of $z$ -classes in reductive groups

Shripad M. Garge, Anupam Singh

Let $k$ be a perfect field such that for every $n$ there are only finitely many field extensions, up to isomorphism, of $k$ of degree $n$ . If $G$ is a reductive algebraic group def…
