Abstract (EN)
In this paper we initiate the investigation of free boundary minimization problems ruled by general singular operators with A_2 weights. We show existence and boundedness of minimizers. The key novelty is a sharp C^1+\gamma regularity result for solutions at their singular free boundary points. We also show a corresponding non-degeneracy estimate.
