On Double 3-Term Arithmetic Progressions
Tom Brown, Veselin Jungić, Andrew Poelstra
In this note we are interested in the problem of whether or not every increasing sequence of positive integers with bounded gaps must contain a double 3-term arithme…

On abelian and additive complexity in infinite words
Hayri Ardal, Tom Brown, Veselin Jungić +1
The study of the structure of infinite words having bounded abelian complexity was initiated by G. Richomme, K. Saari, and L. Q. Zamboni. In this note we define bounded additive co…

A note on edge-colourings avoiding rainbow K_4 and monochromatic K_m
Veselin Jungic, Tomas Kaiser, Daniel Kral
We study the mixed Ramsey number maxR(n,K_m,K_r), defined as the maximum number of colours in an edge-colouring of the complete graph K_n, such that K_n has no monochromatic comple…
