Non-commutative Sylvester's determinantal identity
arXiv:math/0703213
Abstract
Sylvester's identity is a classical determinantal identity with a straightforward linear algebra proof. We present a new, combinatorial proof of the identity, prove several non-commutative versions, and find a -extension that is both a generalization of Sylvester's identity and the -extension of the MacMahon master theorem.
