We illustrate the general theory with a discussion of real hyper-elliptic curves in paragraph 6, real plane curves in paragraph 7, and real trigonal curves in paragraph 8, and end

Another proof of the Riemann-Roch theorem (characteristic zero) which uses the symmetric product is given in. ZARISKI, « A topological proof of the Riemann-Roch

It is plausible, however, that one might bound the number of algebraic families occurring in Corollary 4.4, and therefore get an effective bound on the number
