... A (real) function of $n$ (real) variables is said to be skew-symmetric , if it changes sign whenever any two variables are interchanged: f(x_1,...,x_i,...,x_j,...,x_n) = -f(x_1,...,x_j,...,x_i,...x_n). A skew-symmetric function $f(x_1,...,x_n)$ is decomposable , if there exist functions of one variable $f_1$, ..., $f_n$ such that f(x_1,...,x_n) = \det\Vert f_i(x_j)\Vert_{i,j=1}^n. Problem 1. Find a criterion that a given skew-symmetric function $f(x_1,...,x_n)$ be decomposable. ...
