Central Elements and Determinantal Identities in the Elliptic Quantum Algebra ${\mathcal{A}}_{q,p}({\widehat{\mathfrak{g}\mathfrak{l}}}_N)$

Elliptic quantum algebra is the algebraic structure characterized by the elliptic solution of the Yang-Baxter equation. In this paper, we construct a family of central elements $\mathfrak{z}(z)$ for the elliptic quantum algebra ${\mathcal{A}}_{q,p}({\widehat{\mathfrak{g}\mathfrak{l}}}_N)$ and show that they can be expressed as quantum determinants, yielding an elliptic analogue of the Liouville formula. In addition, we establish determinantal identities, including Jacobi’s ratio theorem and Sylvester’s theorem.
