abstract

• A (2k 1)-dimensional contact Lie algebra is one which admits a one-form ϕ such that ϕ ∧ (dϕ)k ≠ 0. Such algebras have index one, but this is not generally a sufficient condition. Here we show that index-one type-A seaweed algebras are necessarily contact. Examples, together with a method for their explicit construction, are provided. © 2022 Mathematical Sciences Publishers
