7.6 LETTERPLACE

This section describes mathematical notions and definitions used in the experimental LETTERPLACE extension of SINGULAR.

For further details, please, refer to the paper [LL]: Roberto La Scala and Viktor Levandovskyy, "Letterplace ideals and non-commutative Groebner bases", Journal of Symbolic Computation, Volume 44, Issue 10, October 2009, Pages 1374-1393.

All algebras are assumed to be associative $K$-algebras for some field $K$.
