Lower bounds for Estrada Index [PDF]

open access: yesPublications de l'Institut Mathematique, 2008
If G is an (n,m)-graph whose spectrum consists of the numbers ?1, ?2, . . . , ?n, then its Estrada index is EE(G) = ?n i=1 e?i . We establish lower bounds for EE(G) in terms of n and m.

A family of formulas with reversal of high avoidability index [PDF]

open access: yes, 2016
We present an infinite family of formulas with reversal whose avoidability index is bounded between 4 and 5, and we show that several members of the family have avoidability index 5.

Finite p-groups with a Frobenius group of automorphisms whose kernel is a cyclic p-group [PDF]

open access: yes, 2013
Suppose that a finite p-group G admits a Frobenius group of automorphisms FH with kernel F that is a cyclic p-group and with complement H. It is proved that if the fixed-point subgroup CG(H) of the complement is nilpotent of class c, then G has a ...

Slice holomorphic solutions of some directional differential equations with bounded L-index in the same direction

open access: yesDemonstratio Mathematica, 2019
In the paper we investigate slice holomorphic functions F : ℂn → ℂ having bounded L-index in a direction, i.e. these functions are entire on every slice {z0 + tb : t ∈ℂ} for an arbitrary z0 ∈ℂn and for the fixed direction b ∈ℂn \ {0}, and (∃m0 ∈ ℤ+) (∀m ∈

A characterization of holomorphic bivariate functions of bounded index

open access: yes, 2017
The following notion of bounded index for complex entire functions was presented by Lepson. function f(z) is of bounded index if there exists an integer N independent of z, such that max{l:0≤l≤N}|f(l)(z)|l!≥|f(n)(z)|n!for alln. $$ \max\limits_{\{l: 0\leq

A chain rule for the expected suprema of Gaussian processes [PDF]

open access: yes, 2014
The expected supremum of a Gaussian process indexed by the image of an index set under a function class is bounded in terms of separate properties of the index set and the function class.
