For a root system Φ, the set A = {Ar | r ∈ Φ} of additive subgroups Ar over commutative ring K is called a carpet of type Φ if commuting two root elements xr (t), t ∈ Ar and xs(u), u ∈ As, gives a result where each factor ...

A computational study of the secondary destruction of a drop of organic water-coal fuel (OCWS) in a gas flow was carried out. For the first time, the influence of the temperature of an OCWF drop, which has non-Newtonian ...

Let m, n and l be integers with 0 6 l 6 m + n. It is the main purpose of this paper to give an identity for the sum: m∑ a=0 n∑ b=0 a+b>m+n−l Bm−aBn−b (m a )(n b ) a + b + 1 ( a + b + 1 m + n − l ) , where ...

In this paper, we proved some coupled fixed point theorems for Hybrid pair of mappings by using ∆-symmetric covariant mappings in bipolar metric spaces. Also we give some examples which supports our results

The purpose of this paper is to introduce and study strongly m-subharmonic (shm)functions on complex manifolds X ⊂ CN , dimX = n, n 6 N. There are different ways to define shm-functions on complex manifolds: using local ...

Global climate warming challenges the permafrost areas losing the frozen state and stabil- ity. Industrial development and human activity in these regions also contributes to the degradation of permafrost. The construction ...

In the present manuscript, we aim to present a new type of the generalized Voigt function, and investigate its series representations. By using the series representations of our function, we also point out some generating ...
