The bi-Galois conjecture for the twist between Manin's universal quantum groups
Let VVV be a 444-dimensional vector space over k\Bbbkk with basis {x0,x1,x2,x3}\{x_0,x_1,x_2,x_3\}{x0,x1,x2,x3}. Let H=aut‾l(k[x0,x1,x2,x3])H=\underline{\operatorname{aut}}^l(\Bbbk[x_0,x_1,x_2,x_3])H=autl(k[x0,x1,x2,x3]) and…
