The transcendence degree of the reals over certain set-theoretical subfields
Azul Fatalini, Ralf Schindler
It is a well-known result that, after adding one Cohen real, the transcendence degree of the reals over the ground-model reals is continuum. We extend this result for a set of…
Non-vanishing unitary cohomology of low-rank integral special linear groups
Benjamin Brück, Sam Hughes, Dawid Kielak +1
We construct explicit finite-dimensional orthogonal representations of for all of whose invariant vectors are trivial, and…
Finitely generated simple sharply 2-transitive groups
Simon André, Vincent Guirardel
We construct the first examples of infinite sharply 2-transitive groups which are finitely generated. Moreover, we construct such a group that has Kazhdan property (T), is simple,…
New dwarfs around the curly spiral galaxy M63
I. D. Karachentsev, F. Neyer, R. Späni +1
We present a deep (50 hours exposed) image of the nearby spiral galaxy M 63 (NGC 5055), taken with a 0.14-m aperture telescope. The galaxy halo exhibits the known very faint system…
NIP henselian valued fields
Franziska Jahnke, Pierre Simon
We show that any theory of tame henselian valued fields is NIP if and only if the theory of its residue field and the theory of its value group are NIP. Moreover, we show that if $…
On the number of spanning trees a planar graph can have
Kevin Buchin, André Schulz
We prove that any planar graph on vertices has less than spanning trees. Under the restriction that the planar graph is 3-connected and contains no triangle and…
