Kubrak–Travkin's conical resolution inequality

About 5 years old · traced to

Let OK\mathcal O_K be the ring of integers of a finite extension of Qp\mathbb Q_p, let kk be its residue field, and let π ⁣:X→Y\pi\colon X\to Y be a conical resolution over OK\mathcal O_K. The notation X(C)/C×X(\mathbb C)/\mathbb C^\times denotes the homotopy quotient. Kubrak–Travkin's conjecture. For every i≥0i\geq 0,

dim⁡kHdRi([X/Gm]k/k)≥dim⁡FpHsingi(X(C)/C×,Fp).\dim_k H^i_{\mathrm{dR}}([X/\mathbb G_m]_k/k)\geq \dim_{\mathbb F_p}H^i_{\mathrm{sing}}(X(\mathbb C)/\mathbb C^\times,\mathbb F_p).

The i=1i=1 case was attributed to Roman Travkin and the first author as a generalized version of an earlier conjecture. The displayed inequality is the proposed extension to all degrees and remains open in the supplied text.
