what is the minimum n s.t$n$ such that in every 2$2$ - coloring of Kn$K_n$ there exist a monochromatic copy of Cm$C_m$ ?
moreover, what is the minimum n s.t$n$ such that in every r$r$ - coloring of Kn$K_n$ there exist a monochromatic cycle?
I found that the answer to 1 is known, but I don't find it. http://www.mate.unlp.edu.ar/~liliana/lawclique_2016/21.pdf - (page 24)
