The large deviation principle for certain series

Miguel A. Arcones (2004)

ESAIM: Probability and Statistics

Similarity:

We study the large deviation principle for stochastic processes of the form { k = 1 x k ( t ) ξ k : t T } , where { ξ k } k = 1 is a sequence of i.i.d.r.v.’s with mean zero and x k ( t ) . We present necessary and sufficient conditions for the large deviation principle for these stochastic processes in several situations. Our approach is based in showing the large deviation principle of the finite dimensional distributions and an exponential asymptotic equicontinuity condition. In order to get the exponential asymptotic equicontinuity...

Introduction to Stopping Time in Stochastic Finance Theory

Peter Jaeger (2017)

Formalized Mathematics

Similarity:

We start with the definition of stopping time according to [4], p.283. We prove, that different definitions for stopping time can coincide. We give examples of stopping time using constant-functions or functions defined with the operator max or min (defined in [6], pp.37–38). Finally we give an example with some given filtration. Stopping time is very important for stochastic finance. A stopping time is the moment, where a certain event occurs ([7], p.372) and can be used together with...
