Char pp log Ax–Lindemann conjecture

Let f:XAg,Fordf:X\rightarrow\mathscr{A}_{g,\mathbb{F}}^{\mathrm{ord}} be a map from a smooth connected variety, let xX(F)x\in X(\mathbb{F}), and let f/x:X/xAg,F/xf^{/x}:X^{/x}\rightarrow\mathscr{A}_{g,\mathbb{F}}^{/x} be the induced formal map. Let Tf,xAg,F/x\mathscr{T}_{f,x}\subseteq\mathscr{A}_{g,\mathbb{F}}^{/x} be the smallest formal torus through which f/xf^{/x} factors. Char pp log Ax–Lindemann conjecture. There exists a special subvariety of Ag,F\mathscr{A}_{g,\mathbb{F}} whose formal germ at f(x)f(x) has Tf,x\mathscr{T}_{f,x} as an irreducible component. This strengthens the Tate-linear conjecture by recovering it when ff is a locally closed immersion and XX is Tate-linear at xx; the source gives no resolution status.
