Symmetry and Rigidity of Star-Shaped Coxeter Systems
Arijit Mahato, Tushar Kanta Naik, A Rameswar Patro
We provide a complete description of the automorphism group $\Aut (W)$ of a Coxeter group admitting a star-shaped finite Coxeter diagram. We prove that each automorphism decomp…
Linear representations, crystallographic quotients, and twisted conjugacy of virtual Artin groups
Neeraj Kumar Dhanwani, Pravin Kumar, Tushar Kanta Naik +1
Virtual Artin groups were recently introduced by Bellingeri, Paris, and Thiel as broad generalizations of the well-known virtual braid groups. For each Coxeter graph , they defi…
Commutator subgroups and crystallographic quotients of virtual extensions of symmetric groups
Pravin Kumar, Tushar Kanta Naik, Neha Nanda +1
The virtual braid group , the virtual twin group and the virtual triplet group are extensions of the symmetric group , which are motivated by the Alexander…
Congruence subgroups and crystallographic quotients of small Coxeter groups
Pravin Kumar, Tushar Kanta Naik, Mahender Singh
Small Coxeter groups are precisely the ones for which the Tits representation is integral, which makes the study of their congruence subgroups relevant. The symmetric group h…
Nilpotent Lie algebras with two centralizer dimensions over a finite field
Rijubrata Kundu, Tushar Kanta Naik, Anupam Singh
A result of Barnea and Isaacs states that if is a finite dimensional nilpotent Lie algebra with exactly two distinct centralizer dimensions, then nilpotency class of is eit…
Nilpotent Lie Algebras of breadth type
Rijubrata Kundu, Tushar Kanta Naik, Anupam Singh
For a natural number , a Lie algebra over a field is said to be of breadth type if the co-dimension of the centralizer of every non-central element is of dimens…
Virtual planar braid groups and permutations
Tushar Kanta Naik, Neha Nanda, Mahender Singh
Twin groups and virtual twin groups are planar analogues of braid groups and virtual braid groups, respectively. These groups play the role of braid groups in the Alexander-Markov…
Structure and automorphisms of pure virtual twin groups
Tushar Kanta Naik, Neha Nanda, Mahender Singh
Study of stable isotopy classes of a finite collection of immersed circles without triple or higher intersections on closed oriented surfaces is considered as a planar analogue of…
Automorphisms of odd Coxeter groups
Tushar Kanta Naik, Mahender Singh
An odd Coxeter group is one which admits a Coxeter system for which all the exponents are either odd or infinity. The paper investigates the family of odd Coxe…
Some remarks on twin groups
Tushar Kanta Naik, Neha Nanda, Mahender Singh
The twin group is a right angled Coxeter group generated by involutions and having only far commutativity relations. These groups can be thought of as planar analogues…
Conjugacy classes and automorphisms of twin groups
Tushar Kanta Naik, Neha Nanda, Mahender Singh
The twin group is a right angled Coxeter group generated by involutions and the pure twin group is the kernel of the natural surjection from onto the symme…
On the probability distribution associated to commutator word map in finite groups \rom{2}
Tushar Kanta Naik
Let denotes the set of sizes of fibers of non-trivial commutators of the commutator word map. Here, we prove that , for any finite group of nilpotency class $3…
Finite -Groups of Nilpotency Class with Two Conjugacy Class Sizes
Tushar Kanta Naik, Rahul Dattatraya Kitture, Manoj K. Yadav
It is proved that, for a prime and integer , finite -groups of nilpotency class and having only two conjugacy class sizes and exist if and only if $…
Finite -groups of conjugate type
Tushar Kanta Naik, Manoj K. Yadav
We classify finite -groups, upto isoclinism, which have only two conjugacy class sizes and . It turns out that the nilpotency class of such groups is .
