The oriented swap process
Particles labelled 1 · · · n are arranged initially in increasing order. Subsequently, each pair of neighbouring particles that is currently in increasing order swaps according to a Poisson process of rate 1. We analyze the asymptotic behaviour of this process as n → ∞. We prove that the space-time trajectories of individual particles converge (when suitably scaled) to a certain family of rando...
متن کاملSwap logic
We investigate dynamic modal operators that can change the model during evaluation. We define the logic SL by extending the basic modal language with the ♦ modality, which is a diamond operator that in addition has the ability to invert pairs of related elements in the domain while traversing an edge of the accessibility relation. SL is very expressive: it fails to have the finite and the tree ...
متن کاملThe Auslander-Reiten Conjecture for Group Rings
This paper studies the vanishing of $Ext$ modules over group rings. Let $R$ be a commutative noetherian ring and $ga$ a group. We provide a criterion under which the vanishing of self extensions of a finitely generated $Rga$-module $M$ forces it to be projective. Using this result, it is shown that $Rga$ satisfies the Auslander-Reiten conjecture, whenever $R$ has finite global dimension and $ga...
متن کاملThe Lévy swap market model
Models driven by Lévy processes are attractive since they allow for better statistical fitting compared to classical diffusion models. We derive the dynamics of the forward swap rate process in a semimartingale setting and introduce a Lévy swap market model. In order to guarantee positive rates, we model the swap rates as ordinary exponentials. We start with the most distant rate which is drive...
متن کاملSwap Bribery
In voting theory, bribery is a form of manipulative behavior in which an external actor (the briber) offers to pay the voters to change their votes in order to get her preferred candidate elected. We investigate a model of bribery where the price of each vote depends on the amount of change that the voter is asked to implement. Specifically, in our model the briber can change a voter’s preferen...
