 This volume contains refereed and updated versions of papers presented at the International Conference on Algebra and Number Theory held on the occasion of the silver jubilee of the School of Mathematics and Computer/Information Science at the University of Hyderabad (India). There are three survey articles on topics as disparate as the cyclicity problem for division algebras, Ramanujan graphs and supplementary zeroes of \(p\)adic L functions of modular forms. There are three articles that announce results and eighteen original contributions. The section on algebra centers on recent work on quadratic forms and division algebras, though there are also papers on modules of Witt vectors, the HodgeTate conjecture, CalabiYau manifolds, and moduli stacks of vector bundles. The section on number theory centers on automorphic forms and representations. However, here again, there are papers on other themes pertaining to elliptic curves and transcendental number theory. This volume is suitable for young researchers, especially those interested in recent developments in the theory of quadratic and automorphic forms and representations.
