Splitting necklaces and measurable colorings of the real line
Noga Alon, Jarosław Grytczuk, Michał Lasoń +1
A (continuous) necklace is simply an interval of the real line colored measurably with some number of colors. A well-known application of the Borsuk-Ulam theorem asserts that every…
New Unfolded Higher Spin Systems in
Nicolas Boulanger, Dmitry Ponomarev, Ergin Sezgin +1
We investigate the unfolded formulation of bosonic Lorentz tensor fields of arbitrary spin in containing a parity breaking mass parameter. They include deformations of the…
Waiter-Client and Client-Waiter planarity, colorability and minor games
Dan Hefetz, Michael Krivelevich, Wei En Tan
For a finite set , a family of sets and a positive integer , we consider two types of two player, perfect information games with no chance moves.…
Lorentz-violating photons with a mass term
Mauro Cambiaso, Ralf Lehnert, Robertus Potting
Perturbative calculations in quantum field theory often require the regularization of infrared divergences. In quantum electrodynamics, such a regularization can for example be acc…
Compatible Hamilton cycles in random graphs
Michael Krivelevich, Choongbum Lee, Benny Sudakov
A graph is Hamiltonian if it contains a cycle passing through every vertex. One of the cornerstone results in the theory of random graphs asserts that for edge probability $p \gg \…
Time variation of Kepler transits induced by stellar rotating spots - a way to distinguish between prograde and retrograde motion I. Theory
Tsevi Mazeh, Tomer Holczer, Avi Shporer
Some transiting planets discovered by the Kepler mission display transit timing variations (TTVs) induced by stellar spots that rotate on the visible hemisphere of their parent sta…
