In this note I show that a pi-1-2 singleton R of L-degree strictly between 0 and 0# can be obtained so as to be the unique solution to a pi-1-2 formula which provably has at most one solution, in the theory ZFC+(*) where (*) has the approximate strength ...

The $ K(\pi,1)$-property for smooth marked curves over finite fields

Izvestiya: Mathematics, 2015
In recent papers (for instance: [Doc. Math., J. DMV 12, 441--471 (2007; Zbl 1169.11048); J. Reine Angew. Math. 640, 203--235 (2010; Zbl 1193.14041)]) the second author studied the ``$K(\pi, 1)$-property for $p$'' (the definition which uses a Hochschild-Serre spectral sequence is given in \S 1.1 of the present paper) for arithmetic curves whose ...
