Abel's theorem and the allied theory, including the theory of the theta functions
A graduate-level mathematical treatise by Henry Frederick Baker on Abel's theorem, algebraic geometry and theta functions, published by Cambridge University Press in 1897 for mathematicians. Its figures are spare line diagrams of Riemann surfaces: nested and interlocking loops, arrowed closed curves, dotted return paths and small italic labels, useful as abstract linear motifs, looping path forms and diagrammatic notation.
