Title: Webs and $q$-Howe dualities in types $\mathbf{B}\mathbf{C}\mathbf{D}$,
Abstract: We define web categories describing intertwiners for the orthogonal and
symplectic Lie algebras, and, in the quantized setup, for certain orthogonal
and symplectic coideal subalgebras. They generalize the Brauer category, and
allow us to prove quantum versions of some classical type
$\mathbf{B}\mathbf{C}\mathbf{D}$ Howe dualities.
