The moment in a chain of 3 volumes surveying the idea of theta features, this quantity offers emphasis to the targeted homes of the theta services linked to compact Riemann surfaces and the way they result in recommendations of the Korteweg-de-Vries equations in addition to different non-linear differential equations of mathematical physics.

This booklet offers an particular basic building of hyperelliptic Jacobian kinds and is a self-contained creation to the idea of the Jacobians. It additionally ties jointly nineteenth-century discoveries because of Jacobi, Neumann, and Frobenius with fresh discoveries of Gelfand, McKean, Moser, John Fay, and others.

A definitive physique of data and study with reference to theta capabilities, this quantity might be an invaluable addition to person and arithmetic learn libraries.
