Lambda: A Mathematica-package for operator product expansions in vertex algebras

Understand

We give an introduction to the Mathematica package Lambda, designed for calculating $\lambda$-brackets in both vertex algebras, and in SUSY vertex algebras.

• This is equivalent to calculating operator product expansions in two-dimensional conformal field theory.
• The syntax of $\lambda$-brackets is reviewed, and some simple examples are shown, both in component notation, and in $N=1$ superfield notation.
