Stationary Non-equilibrium Solutions for Coagulation Systems

چکیده
Abstract We study coagulation equations under non-equilibrium conditions which are induced by the addition of a source term for small cluster sizes. consider both discrete and continuous equations, allow large class rate kernels, with main restriction being boundedness from above below certain weight functions. The functions depend on two power law parameters, assumptions cover, in particular, commonly used free molecular diffusion limited aggregation kernels. Our result shows that function parameters already determine whether there exists stationary solution presence term. In we find diffusive kernel allows existence solutions while cannot be any such kernel. argument to prove non-existence relies novel lower bound, valid appropriate parameter regime, decay constant flux. obtain optimal upper estimates sizes, model behave asymptotically as model.

Stationary solutions of Liouville equations for non-Hamiltonian systems
We consider the class of non-Hamiltonian and dissipative statistical systems with distributions that are determined by the Hamiltonian. The distributions are derived analytically as stationary solutions of the Liouville equation for non-Hamiltonian systems. The class of non-Hamiltonian systems can be described by a non-holonomic (non-integrable) constraint: the velocity of the elementary phase ...
متن کاملStationary Non-Equilibrium States of Infinite Harmonic Systems
We investigate the existence, properties and approach to stationary non-equilibrium states of infinite harmonic crystals. For classical systems these stationary states are, like the Gibbs states, Gaussian measures on the phase space of the infinite system (analogues results are true for quantum systems). Their ergodic properties are the same as those of the equilibrium states: e.g. for ordered ...
متن کاملBargaining Equilibrium in a Non-Stationary Environment
In this paper we study an alternating-offers bargaining model in which the set of possible utility pairs evolves through time in a non-stationary, but smooth manner. In general there exists a multiplicity of subgame perfect equilibria. However, we show that in the limit as the time interval between two consecutive offers becomes arbitrarily small, there exists a unique subgame perfect equilibri...
متن کاملKinetic theory for non-equilibrium stationary states in long-range interacting systems
We study long-range interacting systems perturbed by external stochastic forces. Unlike the case of short-range systems, where stochastic forces usually act locally on each particle, here we consider perturbations by external stochastic fields. The system reaches stationary states where external forces balance dissipation on average. These states do not respect detailed balance and support non-...
متن کاملTime-Decaying Bandits for Non-stationary Systems
Contents displayed on web portals (e.g., news articles at Yahoo.com) are usually adaptively selected from a dynamic set of candidate items, and the attractiveness of each item decays over time. The goal of those websites is to maximize the engagement of users (usually measured by their clicks) on the selected items. We formulate this kind of applications as a new variant of bandit problems wher...
