Let \(J\) be the Jacobian of the hyperelliptic curve \(Y^{2}=f\left(X^{2}\right)\) over a field \(K\) of characteristic 0 , where \(f\) has odd degree. We shall present an embedding of the group \(J(K) / 2 J(K)\) into the group \(L^{* / L^{* 2}}\) where \(L=K[T] / f(T)\). Since this embedding is der

โฆ Synopsis
An algorithm for constructing a basis of a linear system L(D) on a hyperelliptic curve is described. Algorithms by Cantor and Chebychev for computing in the Jacobian of a hyperelliptic curve are derived as special cases. The final section describes Chebychev's application of his algorithm to elementary integration of elliptic differentials.

We find bounds for the genus of a curve over a field of characteristic p under the hypothesis that the Cartier operator of this curve has low rank and in the case where it is nilpotent. แฎ 2001 Academic Press c w x e.g., 11 .

We show that the minimum number i m (n) of intersections in an n-family of simple closed curves whose elements pairwise intersect at least once and in less than m points satisfies the asymptotic behavior lim n ร i m (n)ร( n 2 )=2.
It is known that large classes of approximately-"nite-memory maps can be uniformly approximated arbitrarily well by the maps of certain non-linear structures. As an application, it was proved that time-delay networks can be used to uniformly approximate arbitrarily well the members of a large class
