Non-Abelian clouds around Reissner-Nordström black holes: the existence line
Eugen Radu, D. H. Tchrakian, Yisong Yang
A known feature of electrically charged Reissner-Nordström-anti-de Sitter planar black holes is that they can become unstable when considered as solutions of Einstein--Yang-Mills t…

Spherically symmetric selfdual Yang-Mills instantons on curved backgrounds in all even dimensions
Eugen Radu, D. H. Tchrakian, Yisong Yang
We present several different classes of selfdual Yang-Mills instantons in all even d backgrounds with Euclidean signature. In d=4p+2 the only solutions we found are on constant cur…
