Abstract: Abstract We analyze the problem of network influence maximization in the uniform independent cascade model: Given a network with N nodes and a probability p for a node to contaminate a neighbor, find a set… read more here.

Abstract: Abstract The century-old extremal problem, solved by Carathéodory and Fejér, concerns a non-negative trigonometric polynomial $T(t) = a_0 + \sum\nolimits_{k = 1}^n {a_k} \cos (2\pi kt) + b_k\sin (2\pi kt){\ge}0$ , normalized by a 0=1,… read more here.

Abstract: We consider in this paper the maximization problem for the quantity $\int_\Omega u(T, x)dx with respect to $u_0 $, where $u$ is the solution of a given reaction-diffusion equation. This problem is motivated by biological… read more here.
