    On a Conjecture of Khoroshkin and Tolstoy
    (Oberwolfach : Mathematisches Forschungsinstitut Oberwolfach, 2022) Appel, Andrea; Gautam, Sachin; Wendlandt, Curtis
    We prove a no-go theorem on the factorization of the lower triangular part in the Gaussian decomposition of the Yangian's universal R-matrix, yielding a negative answer to a conjecture of Khoroshkin and Tolstoy from [Lett. Math. Phys. vol. 36 1996].
