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.

We present new functional equations connecting the counting series of plane and planar (in the sense of Harary and Palmer) dissections. Simple rigorous expressions for counting symmetric r-dissections of polygons and planar S-dissections are obtained.

In this paper we will investigate the edge-chromatic automorphism groups for two classes of graphs. Chromatic automorphism groups have been studied by a number of people, including Chvatal [4] and Baumann et al. [l, 21. Characterizations will be given for these groups. Note that all arithmetic will be done modp, p not necessarily prime. The particular p will be clear from the context. These gra...
