TL;DR

This paper investigates the internal structure of Einstein-Yang-Mills black holes, revealing a generic oscillatory behavior near the singularity and identifying special solutions with simpler inner structures at specific horizon radii.

Contribution

It demonstrates the generic oscillating behavior inside Einstein-Yang-Mills black holes and characterizes the special solutions with Schwarzschild or Reissner-Nordstrom-like structures.

Findings

Generic solutions exhibit infinite oscillations near the singularity.

Exceptional solutions exist at discrete horizon radii with simpler inner structures.

The study advances understanding of black hole internal geometries in Einstein-Yang-Mills theory.

Abstract

It is shown that a generic black hole solution of the SU(2) Einstein-Yang-Mills equations develops a new type of an infinitely oscillating behavior near the singularity. Only for certain discrete values of the event horizon radius exceptional solutions exist, possessing an inner structure of the Schwarzschild or Reissner-Nordstrom type.
