Abstract
We are interested in rings where all 2-absorbing ideals are prime. We call such class of rings 2-AB rings. In this paper, we give a characterization of 2-AB rings, for example, we show that an integral valuation domain R is a 2-AB domain if and only if \(P^2 = P\) for every prime ideal P of R.
