Saturation for flagged skew Littlewood-Richardson coefficients

We define and study a generalization of the Littlewood-Richardson (LR) coefficients, which we call the flagged skew LR coefficients. These
subsume several previously studied extensions of the LR coefficients. We establish the saturation property for these coefficients, generalizing the results of Knutson-Tao and Kushwaha-Raghavan-Viswanath. This talk is based on joint work with Siddheswar Kundu, K.N. Raghavan and Sankaran Viswanath (arXiv:2305.05195).
