Works
Ayyangar had a number of publications, including an article on the Chakravala method where he showed how the method differed from the method of continued fractions. He pointed out that this point was missed by André Weil, who thought that the Chakravala method was only an "experimental fact" to the Indians and attributed general proofs to Pierre de Fermat and Joseph-Louis Lagrange.{{cite book |last=Sridharan |first=Ramaiyengar |title=Science in the West and India |publisher=Himalaya Publishing House, Bombay |year=1998 |author-link=Ramaiyengar Sridharan}}
