A Structural Characterization of Determinantally Equivalent Functions

Harry Sapranidis Mantelos

Let $\Lambda$ be a set and $\mathbb{F}$ a field. Suppose that $K,Q:{\Lambda }^2\to \mathbb{F}$ are two functions such that for any $n\in \mathbb{N}$ and $x_1,x_2,\dots ,x_n\in \Lambda$, the determinants o…
