I am currently writing a review as a thesis project and I must cover black holes and wormholes, static and stationary. For black holes I found this [lecture][1] where black holes are approached from a more mathematical point of view. However, for wormholes I didn't really find much material (except for this [article][2] but I would like to know more). Could you recommend sources that cover wormholes from a more mathematical point of view but without neglecting the physical concepts?
