Adapted metric conjecture for p-sectional hyperbolic sets

From papers

Let XX be a C1C^1 vector field with flow XtX_t, and let Γ\Gamma be a pp-sectional hyperbolic set with invariant splitting TΓM=EFT_\Gamma M=E\oplus F. A metric is required to provide constants μ>0\mu>0 such that, for every xΓx\in\Gamma and t>0t>0, the stable bundle contracts, domination holds, and every pp-dimensional subspace LxFxL_x\subset F_x expands. Adapted metric conjecture. There exists a metric such that, for some constant μ>0\mu>0 and all t>0t>0,

DXtExeμt,|DX_t\mid_{E_x}|\le e^{-\mu t}, DXtEx(DXtFx)1eμt,|DX_t\mid_{E_x}|\cdot\big|(DX_t\mid_{F_x})^{-1}\big|\le e^{-\mu t},

and

pDXt(x)Lx>eμt|\wedge^p DX_t(x)\vert_{L_x}|>e^{\mu t}

for every pp-dimensional linear subspace LxFxL_x\subset F_x. The conjecture proposes that the adapted-metric conclusion previously obtained for sectional hyperbolic sets extends to the more general pp-sectional setting; no resolution is supplied here.
