Sets of range uniqueness for multivariate polynomials and linear functions with rank k
{{output}}
Let F be a set of functions with a common domain X and a common range Y. A set S ⊆ X is called a set of range uniqueness (SRU) for F , if for all f , g ∈ F , f [ S ] = g [ S ] ⇒ f = g . Let P n , k be the set of all real polynomials in ... ...
