alternating polynomial

In algebra, an alternating polynomial is a polynomial ${\\displaystyle f(x_{1},\\dots ,x_{n})}$ such that if one switches any two of the variables, the polynomial changes sign:
${\\displaystyle f(x_{1},\\dots ,x_{j},\\dots ,x_{i},\\dots ,x_{n})=-f(x_{1},\\dots ,x_{i},\\dots ,x_{j},\\dots ,x_{n}).}$
Equivalently, if one permutes the variables, the polynomial changes in value by the sign of the permutation:
${\\displaystyle f\\left(x_{\\sigma (1)},\\dots ,x_{\\sigma (n)}\ ight)=\\mathrm {sgn} (\\sigma )f(x_{1},\\dots ,x_{n}).}$
More generally, a polynomial ${\\displaystyle f(x_{1},\\dots ,x_{n},y_{1},\\dots ,y_{t})}$ is said to be alternating in ${\\displaystyle x_{1},\\dots ,x_{n}}$ if it changes sign if one switches any two of the ${\\displaystyle x_{i}}$ , leaving the ${\\displaystyle y_{j}}$ fixed
