in this note we are going to survey several invariants of finite groups related either to their orders or to generating sets or to lattices of subgroups. some relations among these invariants will be exhibited. special attention will be paid to monotonicity of them.

The object of this paper to derive certain sucient condi-tions for close-to-convexity of certain analytic functions dened on theunit disk  

In 2010, Cilleruelo, Ruzsa, and Vinuesa established a surprising connection between the maximum possible size of generalized Sidon set in first $N$ natural numbers optimal constant an “analogous” problem concerning nonnegative-valued func

the wiener index is a graph invariant that has found extensive application in chemistry. inaddition to that a generating function, which was called the wiener polynomial, who’sderivate is a q-analog of the wiener index was defined. in an article, sagan, yeh and zhang in[the wiener polynomial of a graph, int. j. quantun chem., 60 (1996), 959969] attainedwhat graph operations do to the wiener po...

We consider hyperbolic links that admit alternating projections on surfaces in compact, irreducible 3-manifolds. show that, under some mild hypotheses, the volume of complement such a link is bounded below terms Kauffman bracket func

Statistical characteristics of scattered electromagnetic waves by turbulent magnetized plasma slab with electron density and magnetic field fluctuations are considered via the perturbation method and boundary conditions. Magnetic field fluctuates both in magnitude and direction. Analytical expressions for the component of scattered electric field, correlation functions of the amplitude and phas...
