Title: Littlewood-Richardson coefficients and Newell-Littlewood numbers
Abstract: By inventing the notion of honeycombs, A. Knutson and T. Tao proved the saturation conjecture for Littlewood-Richardson coefficients in 1999. The Newell-Littlewood numbers are a generalization of the Littlewood-Richardson coefficients [Gao-Orelowitz-Yong '21]. In ''stable range'', they are also tensor product multiplicities of classical Lie groups: type B, C and D [Koike ‘89]. By introducing honeycombs on a Möbius strip, I will discuss about the saturation conjecture for Newell-Littlewood numbers posed by S. Gao, G. Orelowitz and A. Yong.
