We calculate the first Hochschild cohomology group of quantum matrices, the quantum general linear group and the quantum special linear group in the generic case when the deformation parameter is not a root of unity. As a corollary, we obtain information about twisted Hochschild homology of these algebras.
Keywords: Quantum matrices, quantum special linear group, derivation, Hochschild cohomology, twisted Hochschild homology
