Self-similarity in random collision processes [PDF]
Physical Review E, 2003 Kinetics of collision processes with linear mixing rules are investigated analytically. The velocity distribution becomes self-similar in the long time limit and the similarity functions have algebraic or stretched exponential tails. The characteristic exponents are roots of transcendental equations and vary continuously with the mixing parameters.

Kalman filtering for self-similar processes [PDF]
Proceedings of the 11th IEEE Signal Processing Workshop on Statistical Signal Processing (Cat. No.01TH8563), 2002 In this paper, we develop a state space representation and Kalman filtering method for self-similar processes. Key components of our development are the concept of multivariate self-similarity and the mathematical framework of scale stationarity. We define multivariate self-similarity as joint self-similarity, in which the self-similarity is governed ...

Dynamics and processing in finite self-similar networks [PDF]
Journal of The Royal Society Interface, 2012 Abstract A common feature of biological networks is the geometrical property of self-similarity. Molecular regulatory networks through to circulatory systems, nervous systems, social systems and ecological trophic networks show self-similar connectivity at multiple scales. We analyse the relationship between topology and signalling in

Representation of self-similar Gaussian processes [PDF]
Statistics & Probability Letters, 2015 We develop the canonical Volterra representation for a self-similar Gaussian process by using the Lamperti transformation of the corresponding stationary Gaussian process, where this latter one admits a canonical integral representation under the assumption of pure non-determinism.

Double hypergeometric Lévy processes and self-similarity [PDF]
Journal of Applied Probability, 2021 AbstractMotivated by a recent paper (Budd (2018)), where a new family of positive self-similar Markov processes associated to stable processes appears, we introduce a new family of Lévy processes, called the double hypergeometric class, whose Wiener–Hopf factorisation is explicit, and as a result many functionals can be determined in closed form.

The Self-Similar Dynamics of Renewal Processes
Electronic Journal of Probability, 2011 We prove an almost sure invariance principle in log density for renewal processes with gaps in the domain of attraction of an α-stable law.

On Entire Moments of Self-Similar Markov Processes [PDF]
Stochastic Analysis and Applications, 2013 It has been shown by Bertoin and Yor (2002) that the law of positive self-similar Markov processes (pssMps) that only jump downwards and do not hit zero in finite time are uniquely determined by their entire moments for which explicit formulas have been derived.

MathematicsA common approach to simulating a Lévy process is to truncate its shot-noise representation. We focus on subordinators and introduce the remainder process, which represents the jumps that are removed by the truncation.
