Elliptic Systems with Nonlinearities of Arbitrary Growth
In this paper we study the existence of nontrivial solutions for the following system of coupled semilinear Poisson equations: −∆u = v , in Ω, −∆v = f(u) , in Ω, u = 0 and v = 0 , on ∂Ω, where Ω is a bounded domain in R . We assume that 0 < p < 2 N−2 , and the function f is superlinear and with no growth restriction (for example f(s) = s e); then the system has a nontrivial (strong) sol...
متن کاملAchievable Rates for Arbitrary Network Topologies with ‘Cheap’ Nodes
In this paper, we derive achievable rates for arbitrary network topologies consisting of ‘cheap’ nodes. A node is labeled ‘cheap’ if its radio can only operate in TDD mode when transmitting and receiving in the same frequency band. Two main results are shown. The first result provides an achievable rate for the channel with either continuous alphabet or discrete channel. The second result provi...
متن کاملAsynchronous optical sampling with arbitrary detuning between laser repetition rates.
A method of asynchronous optical sampling based on free-running lasers with no requirement on the repetition rates is presented. The method is based on the a posteriori determination of the delay between each pair of pulses. A resolution better than 400 fs over 13 ns total delay scan is demonstrated. In addition to the advantages of conventional asynchronous sampling techniques, this method all...
متن کاملSimulating Term Structure of Interest Rates with Arbitrary Marginals
Decision models under uncertainty need to be feeded with scenarios of the interest rate curve. Such scenarios have to comply, as close as possible, with the empirical distribution of each rate. Simulation models of the term structure usually assume that the conjugate distribution of the interest rates is lognormal. Dynamic models, like vector auto-regression, implicitly postulate that the logar...
متن کاملTessellations of random maps of arbitrary genus (Mosäıques sur des cartes aléatoires en genre arbitraire)
We investigate Voronoi-like tessellations of bipartite quadrangulations on surfaces of arbitrary genus, by using a natural generalization of a bijection of Marcus and Schaeffer allowing one to encode such structures by labeled maps with a fixed number of faces. We investigate the scaling limits of the latter. Applications include asymptotic enumeration results for quadrangulations, and typical ...
