Continuous-time random walk
WebDec 10, 2024 · Abstract The general fractional calculus becomes popular in continuous time random walk recently. However, the boundedness condition of the general fractional integral is one of the fundamental problems. It wasn’t given yet. In this short communication, the classical norm space is used, and a general boundedness theorem is presented.

WebTo consider a continuous time random walk, we must first develop a mathematical framework for handling random waiting times between steps, and since these times … WebApr 23, 2024 · In continuous time (with the continuity assumptions we have imposed), such a process is known as a Lévy process, named for Paul Lévy, and also as a continuous-time random walk. For a process with independent increments (not necessarily stationary), the connection with martingales depends on the mean function \( m \) given by \( m(t) = …

And finally since the Poisson process has independent increments we also have that is independent of and so …
In mathematics, a continuous-time random walk (CTRW) is a generalization of a random walk where the wandering particle waits for a random time between jumps. It is a stochastic jump process with arbitrary distributions of jump lengths and waiting times. More generally it can be seen to be a special case of a Markov renewal process.
