SUMMARY |
|
|
Let $A, B$ be polynomial rings over a field $k$, and $I\subseteq
A, J\subseteq B$ proper homogeneous ideals. We analyze the associated
primes of powers of $I+J\subseteq A\otimes_k B$ given the data on the
summands. The associated primes of large enough powers of $I+J$ are
determined. We then answer positively a question due to I. Swanson and R.
Walker about the persistence property of $I+J$ in many new cases. This is a
joint work with Quang Hoa Tran.
