On Skew-holomorphic Jacobi Forms,Let ., . be positive integers and let . be odd. Let . (mod 2.) be an integer. The theta function. where .(.) := .., . ∈ ?, satisfies the heat equation.and further it satisfies the following transformation law:.where ..(.) := .., . ∈ ?. The Poisson summation formula gives

On the Average of the Sum-of-odd-divisors Function,term in the average .(.) = Σ.’(.). We apply the method of averaging over suitable arithmetic progressions to get an extension of the Ω-results obtained by Y.-F.S. Pétermann in the case of the sum-of-divisors function, the classical .(.).

The Addition Law on Hyperelliptic Jacobians,lex numbers, this can be done using theta function identities. Abstractly, the group law was written down by Cantor [1]. As observed by Koblitz [2], this makes it possible to use the set of points on the Jacobian of a hyperelliptic curve (or more succintly, a hyperelliptic Jacobian) over a finite field as the basis of a public-key cryptosystem.
