Hurewicz fibration conjecture for randomized simplicial sets

From papers

Let FF be a simplicial set, with geometric realization F|F|, and let L(F)L(F) denote its realization in the deterministic construction. Let \mathbbmL(F)\mathbbm{L}(F) be the randomized realization of the underlying pre-simplicial set, with probability-law map to the ordinary realization F\|F\|.

Hurewicz fibration conjecture. The maps

L(F)Fand\mathbbmL(F)FL(F) \to |F| \qquad\text{and}\qquad \mathbbm{L}(F) \to \|F\|

are Hurewicz fibrations.

This conjecture proposes a fibration enhancement of the comparison maps between the paper's randomized and ordinary realizations. The preceding results establish homotopy-equivalence properties for the corresponding maps in the pre-simplicial setting, but do not establish the stronger Hurewicz fibration assertion.
