The epsilon-loss local Mizohata–Takeuchi conjecture

Let BRB_R be the ball of radius RR centered at the origin, let T\mathbb{T} be the relevant family of tubes, and write w(T)w(T) for the weight of a tube. Under the hypotheses of the Mizohata–Takeuchi conjecture, local Mizohata–Takeuchi conjecture. For every ϵ>0\epsilon>0,

BREg(x)2w(x)dxϵRϵsupTTw(T)Σg(ω)2dσ(ω).\int_{B_R}|Eg(x)|^2w(x)\,dx\lesssim_{\epsilon}R^{\epsilon}\sup_{T\in\mathbb{T}}w(T)\int_{\Sigma}|g(\omega)|^2\,d\sigma(\omega).

This is the localized epsilon-loss version proposed after a counterexample showed logarithmic failure of the scale-invariant local estimate. The source explicitly states that this conjecture remains open.
