Abstract

This is the continuation of the article by the author that proves a broader class of families admitting the theorem of restriction of sections other than Abelian varieties and gives new examples of pseudo-Néron models. In this work, we show that the techniques in the first paper give more general results and more examples such that the theorem of restriction of sections holds. Also, we give counter examples to show that the non-existence of rational curves is not a necessary condition for such theorems. As an application, we prove a result for Hodge classes of a certain weight which is similar to the result about sections.
