Distributional properties of exponential functionals of Levy processes [PDF]

open access: yes, 2012
We study the distribution of the exponential functional $I(\xi,\eta)=\int_0^{\infty} \exp(\xi_{t-}) \d \eta_t$, where $\xi$ and $\eta$ are independent L\'evy processes.

Meshfree Exponential Integrators

open access: yesSIAM Journal on Scientific Computing, 2013
For the numerical solution of time-dependent partial differential equations, a class of meshfree exponential integrators is proposed. These methods are of particular interest in situations where the solution of the differential equation concentrates on a small part of the computational domain which may vary in time. For the space discretization, radial

Integral Equations and Exponential Trichotomy of Skew-Product Flows

open access: yesAdvances in Difference Equations, 2011
We are interested in an open problem concerning the integral characterizations of the uniform exponential trichotomy of skew-product flows. We introduce a new admissibility concept which relies on a double solvability of an associated integral equation ...

A possible deformed algebra and calculus inspired in nonextensive thermostatistics [PDF]

open access: yes, 2004
We present a deformed algebra related to the q-exponential and the q-logarithm functions that emerge from nonextensive statistical mechanics. We also develop a q-derivative (and consistently a q-integral) for which the q-exponential is an eigenfunction ...

Exponential decay estimates for Singular Integral operators [PDF]

open access: yes, 2013
The following subexponential estimate for commutators is proved |[|\{x\in Q: |[b,T]f(x)|>tM^2f(x)\}|\leq c\,e^{-\sqrt{\alpha\, t\|b\|_{BMO}}}\, |Q|, \qquad t>0.\] where $c$ and $\alpha$ are absolute constants, $T$ is a Calder\'on--Zygmund operator, $M ...

A New Precursor Integral Method for Solving Space-Dependent Kinetic Equations in Neutronic and Thermal-Hydraulic Coupling System

open access: yesScience and Technology of Nuclear Installations, 2020
The accurate prediction of the neutronic and thermal-hydraulic coupling system transient behavior is important in nuclear reactor safety analysis, where a large-scale nonlinear coupling system with strong stiffness should be solved efficiently.

A novel exponential‐type anti‐windup method applied to the power converter in marine electrical propeller system

open access: yesIET Power Electronics, 2022
This paper proposes a novel exponential anti‐windup method for a high‐proportional‐load marine electrical propeller system, allowing the system to respond to changes in working conditions that would make the control system operate in the open‐loop state ...
