The Slater variety of this entity describes a system of fermions which is antisymmetric under they exchange of identical fermions. A value of zero for the Wronskian type of this entity implies linear dependence for a set of analytic functions, and the Jacobian variety is used while changing variables to perform multiple integration over a given domain. Sarrus' scheme is a method for computing these values, which are zero for singular matrices. For 10 points, name this mathematical object, which, for a 2x2 matrix, is equal to ad-bc.
