图 G 的合适的边着色被叫非循环如果没有 2-colored,在 G 骑车。G 的非循环的色彩的索引,由 x 表示了(G) ,是颜色的最少的数字以便 G 有非循环的边 k 着色。让 G 是有最大的度和尺寸 g (G) 的一张图,并且让 2 是的 1 r 一个整数。在这份报纸,在那里存在,这被显示出经常的 c > 0 以便如果 $g (G) \\geqslant \\frac {{ c\\Delta }}{ r } \\log \\left ({ \\Delta ^ 2 /r } \\right

We review the Reidemeister, Ray-Singer’s analytic torsion and the Cheeger-Mller theorem. We describe the analytic torsion of the de Rham complex twisted by a
Let ind(c) be the Morse index of a closed geodesic c in an(n+1)-dimensional Riemannian manifold M.We prove that an oriented closed geodesic c is unstable if n +
This paper concerns two-person zero-sum games for a class of average-payoff continuous-time Markov processes in Polish spaces.The underlying processes are deter
We consider the decay parameter, invariant measures/vectors and quasi-stationary dis- tributions for 2-type Markov branching processes. Investigating such prope
In this paper we study the number of rational points on some curves over finite fields. Moreover, zeta functions of the associated function fields are evaluated
Intuitively, non-smooth points might look like exposed points. However, in this paper we show that real Banach spaces having dimension greater than or equal to
The study of the rodent fluctuations of the North was initiated in its modern form with Elton’s pioneering work.Many scientific studies have been designed to c
The paper is devoted to the analysis of certain dynamical properties of a family of iterative Newton type methods used to find roots of non-linear equations. We
