Denis–Mordell–Lang conjecture for q-varieties and Drinfeld modules

Assume that (F,Φ)(F,\Phi) is an AA-module, HotiFH ot i F is a qq-variety, and Γ=Ax1++Axr\Gamma=Ax_1+\ldots+Ax_r is generated by elements of FF. Define the division hull

Γ=xotiFoti such that aot=0otiA with Φa(x)otiΓ.\overline{\Gamma}={x ot i F ot i\text{ such that }\exists a ot=0 ot i A\text{ with }\Phi_a(x) ot i\Gamma}.

Denis–Mordell–Lang conjecture. There exists an AA-module GotiHG ot i H such that

[GotiΓ:GotiH]<.[G ot i\bigcap\overline{\Gamma}:G ot i\bigcap H]<\infty.

The source says this conjecture implies the preceding Denis–Faltings analogue and identifies it as an analogue of the Mordell–Lang conjecture. Its resolution status is not specified.
