Title  Generic initial ideals and fibre products.  Author(s)  Aldo Conca, Tim Römer  Type  Article in Journal  Abstract  We study the behavior of generic initial ideals with respect to fibre products. In our main result we determine the generic initial ideal of the fibre product with respect to the reverse lexicographic order. As an application we compute explicitly the generic initial ideal of a fibre product in a special case. We also prove that the fibre product of two graded ideals is componentwise linear if and only if both ideals have this property.  ISSN  00306126
