Viral or buzz marketing takes advantage of communication linkages to propagate positive in uence regarding a product or service. TelE-commerce is an ideal domain within which to study viral marketing, because communication linkages can be observed. In this paper, we follow a new telE-commerce service. In particular, we observe how the communication networks of existing customers in uence the ra...

In the following statement, gr denotes the category of free groups of finite rank, VecQ the category of Q-vector spaces, a : gr→ VecQ the composition of abelianisation and rationalisation (a(G) = Gab ⊗ Q) and Λ the j-th exterior power. As usual, Fr is a free group of rank r; gr-Mod is the category of functors from gr to VecQ. Theorem 1. Let F : gr → VecQ be a polynomial functor of degree d and ...

Mobile government (M-government) is a new delivery channel for governments to provide timely information and services ubiquitously to residents, businesses and other government departments through mobile devices. Developing countries have a higher mobile penetration rate than the fixed line internet rates which opens doors of opportunities for these countries to bridge the digital gab and gain ...

G(u,u',u") = 0, (1) where u = u(x, x,..., x), and u', u" denote all the first and second partial derivatives of u. For simplicity we will assume here that both u and G are scalars and denote by ua, uab, the partial derivatives dau and respectively dahu; a,b =1,2, ..., n+1. Let u (x) be a given solution of (1). Our equation is said to be elliptic or hyperbolic at u°(x) according to whether the (...

We consider dissipative relativistic fluid theories on a fixed flat, globally hyperbolic, Lorentzian manifold (R3T,gab). We prove that for all initial data in a small enough neighborhood of the constant equilibrium states ~in an appropriate Sobolev norm!, the solutions evolve smoothly in time forever and decay exponentially to some, in general undetermined, constant equilibrium state. To prove ...
