I'm looking for articles that discuss the authorship of works attributed to Śaṅkarācārya .  Which works are considered genuinely by him and which are not.

Even better are articles that discuss the authorship  and dating of the Dakṣiṇāmūrtistotram .  Whether that is considered genuinely by Śaṅkarācārya or whether that is a much later work.

Many thanks,

Harry Spier
