Algebraic Geometry and its Applications

This Festschrift in honor of Shreeram Abhyankar's 60th birthday includes 32 of the invited papers presented at the conference in his honor held in June 1990 at Purdue University. Topics covered include: mathematics in India, algebraic curves, algebraic surfaces, analytic functions, groups and coverings, Young tableaux, commutative algebra, and computational algebraic geometry.
