Addition laws on Jacobian varieties of plane algebraic curves. (English. Russian original) Zbl 1132.14024

The authors study the sigma functions for Jacobians of plane algebraic curves and apply these results to the study of addition laws of abelian functions. They find explicit addition formulas for hyperelliptic abelian functions and give a construction of second-order linear differential equations that hold for sigma functions of high genera. Then equations can be interpreted as multidimensional heat equations in a nonholonomic frame.
