Let $X$ be a hyper-Kähler variety, and let $\mathfrak{h}(X)$ denote its motive. For each degree $i$ and prime $ell$, let $\mathbf{G}_{\ell,i}(X)$ be the $ell$-adic algebraic monodr…

Let $S$ be the base of the family considered in the paper. A special subvariety is a closed irreducible complex subvariety maximal among those having a fixed generic Mumford–Tate g…

Let $S$ be the base of the family considered in the paper, and for a subvariety $Z\subset S$ let $G_Z$ and $G_Z^{AH}$ be its generic Mumford–Tate and generic absolute Mumford–Tate…

Let $X$ be a smooth projective variety over $K$, let $G_X^{AH}$ denote its absolute Mumford–Tate group, and let $G_{\ell,X}$ denote its $\ell$-adic algebraic Galois group. Absolute…

Let $X$ be as above, let $H$ be the Mumford–Tate group, and let $H^{\operatorname{sc}}$ be the simply connected cover of its derived group. Let…
