"Vedic Mathematics" is a book by Bharati Krishna Tirthaji, who served as the Shankaracharya of Sringeri Mutt from 1921-1925, and as the Shankaracharya of Govardhana Mutt from 1925 until his death in 1960. It was during his time in the latter position that he gave a series of lectures in which he claimed to have discovered a set of 16 Sutras in the Parishishta (appendix) of the Atharvana Veda which describe advanced mathematical techniques. He then wrote a book on the same subject, known as "Vedic Mathematics", which was published posthumously in 1965.
But most scholars don't accept the authenticity of the book, for reasons described in journal paper. For one thing, published editions of the Parishishta of the Atharvana Veda do not contain these 16 Sutras. Also, the mathematical techniques that Bharati Krishna Tirthaji describes are reminiscent of European arithmetic tricks. (See here for the real mathematics of the Vedic period.). But my question is, what does Govardhana Mutt believe about the authenticity of the book, given that Bharati Krishna Tirthaji was one of their Shankaracharyas? I would ask about Sringeri Mutt as well, except that Bharati Krishna Tirthaji lectured on this subject while he was the Shankaracharya of Govardhana Mutt.
Bharati Krishna Tirthaji's shishya Manjula Tirvedi says this in her introduction to the "Vedic Mathematics" book:
Obviously these formulas are not to be found in the present recessions of Atharvaveda; they were actually reconstructed, on the basis of intuitive revelation, from materials scattered here are there in the Atharvaveda.
But have any Shankaracharyas of Govardhana Mutt who came after Bharati Krishna Tirthaji's time discussed the book?
