Query: Quantum symmetric pairs at roots of $1$   A quantum symmetric pair is a quantization of the symmetric pair of universal
enveloping algebras. Recent development suggests that most of the theory for
quantum groups can be generalised to the setting of quantum symmetric pairs. In
this paper, we study the $\imath$quantum group at roots of $1$. We generalize
Lusztig's quantum Frobenius morphism in this new setting. We define the small
$\imath$quantum group and compute its dimension.
