Characteristic function of a meromorphic function and its derivatives
In this paper, some results of Singh, Gopalakrishna and Kulkarni (1970s) have been extended to higher order derivatives. It has been shown that, if $sumlimits_{a}Theta(a, f)=2$ holds for a meromorphic function $f(z)$ of finite order, then for any positive integer $k,$ $T(r, f)sim T(r, f^{(k)}), rrightarrowinfty$ if $Theta(infty, f)=1$ and $T(r, f)sim (k+1)T(r, f^{(k)}), rrightarrowinfty$ if $Th...
متن کاملCharacteristic Subobjects in Semi-abelian Categories
We extend to semi-abelian categories the notion of characteristic subobject, which is widely used in group theory and in the theory of Lie algebras. Moreover, we show that many of the classical properties of characteristic subgroups of a group hold in the general semi-abelian context, or in stronger ones.
متن کامل“humans Inside” as the Key Characteristic of Service Systems
This paper presents a definition of service systems that is simple, comprehensive, actionable, and, most of all, differentiates service from product systems. We propose as the defining characteristic of a service system the significant presence of human beings, either as individuals or as organizations, as part of the service system during the time of use. We hypothesize that the main implicati...
متن کاملCharacteristic Numbers of a Homogeneous Space
Let G be a compact connected Lie group with maximal torus T , and H a closed subgroup containing T . We work out the Atiyah-Bott-Berline-Vergne localization formula for the homogeneous space G/H under the natural action of the maximal torus T . The computation gives explicit formulas for the ordinary and equivariant characteristic numbers of a homogeneous space. Let G be a compact connected Lie...
متن کاملProviding A New Characteristic for Overcurrent Relays
This with the integration of distributed generation (DG) to meshed distribution systems, the operating time of the protective system becomes a major concern in order to avoid nuisance DG tripping. This paper proposes a new tripping characteristic for directional overcurrent relays (DOCRs) that can achieve a higher possible reduction of overall relays operating time in meshed distribution networ...
