报告摘要：We apply the recently introduced idempotents for the Sergeev superalgebra to construct quantum immanants for the queer Lie superalgebra $q_N$ as central elements of its universal enveloping algebra. We prove a universal Capelli identity for $q_N$ and use it to calculate the images of the quantum immanants under the action of $q_N$ in differential operators. We show that the Harish-Chandra images of the quantum immanants coincide with the factorial Schur $Q$-polynomials. This is joint work with Alexander Molev
