To observe the tenth anniversary of the founding of the Ramanujan Mathematical Society, an international conference on Discrete Mathematics and Number Theory was held in January 1996 in Tiruchirapalli, India. This volume contains proceedings form the number theory component of that conference. Papers are divided into four groups: arithmetic algebraic geometry, automorphic forms, elementary and analytic number theory and transcendental number theory. This work deals with recent progress in current aspects of number theory and covers a wide variety of topics.

Arithmetic Algebraic Geometry

• D. Bertrand -- Relative splitting of one-motives
• J.-L. Colliot-Thélène -- The Hasse principle in a pencil of algebraic varieties
• H. Darmon -- Stark-Heegner points over real quadratic fields
• F. Diamond -- On the Hecke action on the cohomology of Hilbert-Blumenthal surfaces
• M. R. Murty -- The ABC conjecture and exponents of class groups of quadratic fields
• W. Schmidt -- Heights of points on subvarieties of ${\mathbb G}_m^n$
• J. Yu and J.-K. Yu -- A note on a geometric analogue of Ankeny-Artin-Chowla's conjecture

Automorphic Forms

• S. Jayasree and R. Tandon -- Determinant of representations of division algebras of prime degree over local fields
