In the present paper, we study the growth properties of entire functions of several complex variables. The characterizations of lower order of entire functions of several complex variables have been obtained in terms of their Taylor’s series coefficients. Also we have obtained some inequalities between order, type, maximum term and central index of entire functions of several complex variables.

Introduction Migraine is a common and very disabling neurological disease. It typically causes severe throbbing pain or pulsing sensation, usually on one side of the head. It's often accompanied by nausea, vomiting, extreme sensitivity to light sound. According definition headache, should be located in head face above orbitomeatal line. Beyond this classical view, recent evidence has shown that...

A finite simplicial graph Γ determines a right-angled Artin group GΓ, with generators corresponding to the vertices of Γ, and with a relation vw = wv for each pair of adjacent vertices. We compute the lower central series quotients, the Chen quotients, and the (first) resonance variety of GΓ, directly from the graph Γ.
