We study foliations with transverse CR structure and their transverse Kohn-Rossi cohomology. For nondegenerate CR foliations with transverse pseudohermitian structure we build an adapted connection which generalizes the Webster connection of a CR fol

We study the interplay between CR structures on real Lie algebras and G-Lie foliations (in the sense of E. Fedida [4]). We show that the transverse KohnRossi cohomology of a complete G-Lie foliation F with transverse CR structure and dense leaves is

In this paper, we establish some refinements and reverses of the celebrated F´ejer’s inequalities for the general case of functions defined on linear spaces. The obtained bounds are in terms of the Gˆateaux lateral derivatives. Some application

Some sharp trapezoid and midpoint type inequalities for Lipschitzian bifunctions defined on a closed disk in Euclidean sense are obtained by the use of polar coordinates. Also, bifunctions whose partial derivative is Lipschitzian are considered. A ne

In this paper, some new inequalities Hermite-Hadamard type are obtained for functions whose nth derivatives in absolute value are s-convex functions. From our results, several inequalities of Hermite-Hadamard type can be derived in terms of functions

In this paper, the notion of harmonic symmetricity of functions is introduced. A new identity involving harmonically symmetric functions is established and some new Fejer type integral inequalities are presented for the class of harmonically convex f
