Extensions of modules over a class of Lie conformal algebras $W (b)$

Kaijing Ling, Lamei Yuan

Let $W (b)$ be a class of free Lie conformal algebras of rank $2$ with $C [\partial]$ -basis $L, H$ and relations \begin{eqnarray*} [L_λL]=(\partial+2λ)L,\ \ [L_λH…

Extensions of Schrödinger-Virasoro conformal modules

Lamei Yuan, Kaijing Ling

In this paper, we study extensions between two finite irreducible conformal modules over the Schrödinger-Virasoro conformal algebra and the extended Schrödinger-Virasoro conformal…
