DOI: 10.1007/s10440-020-00336-8

Abstract: This paper uses Lie symmetry methods to analyze boundary crossing probabilities for a large class of diffusion processes. We show that if the Fokker–Planck–Kolmogorov equation has non-trivial Lie symmetry, then the boundary crossing identity exists… read more here.

DOI: 10.1016/j.actamat.2019.01.053

Abstract: Abstract One of the most efficient proxy methods for paleoclimatology consists of obtaining data previously preserved within polar ice cores. Models for past climate reconstruction are based in particular on the characterization of entrapped gases… read more here.

DOI: 10.1016/j.jkss.2019.05.002

Abstract: Abstract Jump–diffusion processes involving diffusion processes with discontinuous movements, called jumps, are widely used to model time-series data that commonly exhibit discontinuity in their sample paths. The existing jump–diffusion models have been recently extended to… read more here.

DOI: 10.1016/j.jmaa.2019.07.044

Abstract: Abstract In this paper, we investigate the tail distribution of a fundamental class of one-dimensional diffusion processes. Based on the techniques of the Malliavin calculus, we obtain explicit estimates for tail distributions. Some examples and… read more here.

DOI: 10.1016/j.jmaa.2019.123624

Abstract: The spectral gap is estimated for measure-valued diffusion processes induced by the intrinsic/extrinsic derivatives on the space of finite measures over a Riemannian manifold. This provides explicit exponential convergence rate for these processes to approximate… read more here.
