Projective normality of abelian varieties

Jaya N. Iyer

We show that ample line bundles L on a g-dimensional simple abelian variety, with h^0(L)> 2^g.g!, give projectively normal embeddings, for all g>0.

Abelian Varieties into 2g+1-dim.Linear Systems

Jaya N. Iyer

We show that polarisations of type (1,...,1,2g+2) on g-dimensional abelian varieties are $never$ very ample, if $g \geq 3$ . This disproves a conjecture of Debarre, Hulek and Sp…

Projective normality of Abelian threefolds

Jaya N. Iyer

In this article, we show that very ample line bundles of type (1,1,d) on an abelian threefold A, with NS(A)\simeq \ze, give projectively normal embeddings, if d=22,26 or when d\geq…

Line bundles of type (1,,,1,2,,,2,4,,,4) on Abelian Varieties

Jaya N. Iyer

We show birationality of the morphism associated to line bundles $L$ of type $(1, ..., 1, 2, ..., 2, 4, ..., 4)$ on a generic $g -$ dimensional abelian variety into its complete linear syste…
