What reading level is A New Proof of Torellis Theorem book?
To quickly assess the difficulty of the text, read a short excerpt:
By virtue of Riemann's theorem it follows that the image in C^ under the map " --^ of (g-l)-tuples of points on X, is determined up to a trans- lation by the period matrix (TriE; A), since it is the set of zeros of 0(u; A) . Thus the sets V/^~ are determined as the zero manifolds of a first-order theta-functions. We shall now drav; an interesting conclusion from the irreduc- Ibility of W^' . Assiome that, in the period matrix, (7riE, A) A decomposes into a direct sum \0 A^J where A^ is an nXn m...atrix. It is readily seen from the definition that in this case 29 e(u; A) = . ^(v; A^)b(w; A^ ), ^^Jhere v is an n-vector, w is a (g-n)-vector^ and u = (v, . .. ;V^, v;, . .. , \^^~^) . Nov/, since W^~ is the zero a manifold of ^{u; A) for some a, it follows that &(v; A, ) vanishes identically on a full neighborhood of W^", but not everywhere, since the zeros of :(v; A ) and 6;(w; A^) do not coincide. This contradicts the irreducibility of W^~, and we a conclude Theorem : If {vlE; A) is a period matrix v/ith respect to a canonical homology basis on a closed Riemann surface, then A is not symplectically equivalent to a direct sum .
