Some nonlinear weakly singular integral inequalities with two variables and applications.
Disjoint triangles and quadrilaterals in a graph
Let n, s and t be three integers with s ≥ 1, t ≥ 0 and n = 3s + 4t. Let G be a graph of order n such that the minimum degree of G is at least (n + s)/2. Then G contains a 2-factor with s + t components such that s of them are triangles and t of them are quadrilaterals.
Disjoint 5-cycles in a graph
We prove that if G is a graph of order 5k and the minimum degree of G is at least 3k then G contains k disjoint cycles of length 5.

Regularity of powers of binomial edge ideals of complete multipartite graphs
Let be a complete multipartite graph on with and being its binomial edge ideal. It is proved that the Castelnuovo-Mumford regularity is for any positive integer .
Yetter-Drinfeld-Long bimodules are modules
Let be a finite-dimensional bialgebra. In this paper, we prove that the category of Yetter-Drinfeld-Long bimodules, introduced by F. Panaite, F. Van Oystaeyen (2008), is isomorphic to the Yetter-Drinfeld category over the tensor product bialgebra as monoidal categories. Moreover if is a finite-dimensional Hopf algebra with bijective antipode, the isomorphism is braided. Finally, as an application of this category isomorphism, we give two results.
Hopf algebra structure with two sided invertible 2-cocycle
In this paper, we study the type Hopf algebras and present its braided and quasitriangular Hopf algebra structure. This generalizes well-known results on and type Hopf algebras. Finally, the classification of type Hopf algebras is given.
