The death of Frank Ramsey in January 1930 just before his twenty-seventh birthday, was the last nail coffin Cambridge school mathematical logic.

In this paper, using the identity proved [43]in for fractional integrals, some new Ostrowski type inequalities for Riemann-Liouville fractional integrals of functions of two variables are established. The established results in this paper generalize those results proved in [43].

In this note, we show that one of the arguments used by Moazzami for computing the tenacity of the third Harary graph is wrong and then improve the proof. © 2014 Published by Elsevier B.V.

Inequalities are obtained using P0-simple functionals. Applications to Lipschitzian mappings are given.
