Abstract

Let σV=k0σkV\bigwedge_\sigma V=\bigoplus_{k\geq 0}\bigwedge_\sigma^kV be the quantum exterior algebra associated to a finite-dimensional braided vector space (V,σ)(V,\sigma). For an algebra A\mathfrak{A}, we consider the convolution product on the graded space k0Hom(σkV,σkVA)\bigoplus_{k\geq 0}\mathrm{Hom}\big(\bigwedge_\sigma^kV,\bigwedge_\sigma^kV\otimes \mathfrak{A}\big). Using this product, we define a notion of quantum minor determinant of a map from VV to VAV\otimes \mathfrak{A}, which coincides with the classical one in the case that A\mathfrak{A} is the FRT algebra corresponding to Uq(slN)U_q(\mathfrak{sl}_N). We establish quantum Laplace expansion formulas and multiplicative formulas for these determinants.
