When every principal ideal is flat

When every $P$-flat ideal is flat

In this paper‎, ‎we study the class of rings in which every $P$-flat‎ ‎ideal is flat and which will be called $PFF$-rings‎. ‎In particular‎, ‎Von Neumann regular rings‎, ‎hereditary rings‎, ‎semi-hereditary ring‎, ‎PID and arithmetical rings are examples of $PFF$-rings‎. ‎In the context domain‎, ‎this notion coincide with‎ ‎Pr"{u}fer domain‎. ‎We provide necessary and sufficient conditions for‎...

Rings with Every Proper Image a Principal Ideal Ring

The main result of this paper states that if R is a right Noetherian right bounded prime ring such that nonzero prime ideals are maximal and such that every proper homomorphic image of R is a principal right ideal ring then R is right hereditary. In [10, Theorem 8] it is proved that if R is a right bounded prime ring of finite right Goldie dimension such that every proper homomorphic image is a...

Rings of Continuous Functions in Which Every Finitely Generated Ideal is Principal

When every multilinear mapping is multiple summing

In this paper we give a systematized treatment to some coincidence situations for multiple summing multilinear mappings which extend, generalize and simplify the methods and results obtained thus far. The application of our general results to the pertinent particular cases gives several new coincidences as well as easier proofs of some known results.

Every calling is great when greatly pursued.

This year, every political pundit is focused on the U.S. Presidential campaign, namely the incumbent Republican team vs. the Democratic ticket (yet to be named), and the recently announced Independent candidate. The incumbent, as well as each prospective candidate, is on the stump, raising campaign funds, spouting rhetoric from podiums in universities, town squares, and televised debates, and a...
