Classification of contact seaweeds

Vincent E. Coll, Nicholas Russoniello

A celebrated result of Gromov ensures the existence of a contact structure on any connected, non-compact, odd dimensional Lie group. In general, such structures are not invariant u…

Contact seaweeds II: type C

Vincent E. Coll, Nicholas Russoniello

This paper is a continuation of earlier work on the construction of contact forms on seaweed algebras. In the prequel to this paper, we show that every index-one seaweed subalgebra…

On toral posets and contact Lie algebras

Nicholas W. Mayers, Nicholas Russoniello

A dimensional Lie algebra is called contact if it admits a one-form such that Here, we extend recent work to describe a combinatorial procedure…

Seaweed algebras

Alex Cameron, Vincent E. Coll, Nicholas Mayers +1

The index of a Lie algebra is an important algebraic invariant, but it is notoriously difficult to compute. However, for the suggestively-named seaweed algebras, the computation of…

The breadth of Lie poset algebras

Alex Cameron, Vincent E. Coll, Nicholas Mayers +1

The breadth of a Lie algebra is defined to be the maximal dimension of the image of , for . Here, we initiate an investigation into the breadth of th…

Contact Lie poset algebras

Vincent Coll, Nicholas Mayers, Nicholas Russoniello

We provide a combinatorial recipe for constructing all posets of height at most two for which the corresponding type-A Lie poset algebra is contact. In the case that such posets ar…

Contact Seaweeds

Vincent E. Coll, Nicholas Mayers, Nicholas Russoniello +1

A ()dimensional contact Lie algebra is one which admits a one-form such that . Such algebras have index one, but this is not generally a sufficient…

The evolution of the spectrum of a Frobenius Lie algebra under deformation

Vincent E. Coll, Nicholas Mayers, Nicholas Russoniello

The category of Frobenius Lie algebras is stable under deformation, and here we examine explicit infinitesimal deformations of four and six dimensional Frobenius Lie algebras with…

The index of nilpotent Lie poset algebras

Vincent Coll, Nicholas Mayers, Nicholas Russoniello

We establish combinatorial formulas for the index of a class of matrix Lie algebras whose matrix forms are encoded by strict partial orderings.

Classification of Frobenius, two-step solvable Lie poset algebras

Vincent Coll, Nicholas Mayers, Nicholas Russoniello

We show that the isomorphism class of a two-step solvable Lie poset subalgebra of a semisimple Lie algebra is determined by its dimension. We further establish that all such algebr…
