    New combinatorial formulae for nested Bethe vectors
    (arXiv, 2025) Kosmakov, Maksim; Tarasov, Vitaly; Mathematical Sciences, School of Science
    We give new combinatorial formulae for vector-valued weight functions (off-shell nested Bethe vectors) for the evaluation modules over the Yangian Y (gl_4). The case of Y (gl_n) for an arbitrary n is considered in the forthcoming paper [KT].
