%0 Journal Article %T Some surfaces with maximal Picard number %A Arnaud Beauville %J Mathematics %D 2013 %I arXiv %X For a smooth complex projective variety, the rank of the N\'eron-Severi group is bounded by the Hodge number h^{1,1}. Varieties with rk NS = h^{1,1} have interesting properties, but are rather sparse, particularly in dimension 2. We discuss in this note a number of examples, in particular those constructed from curves with special Jacobians. %U http://arxiv.org/abs/1310.3402v2
