Applications of factorization embeddings for Lévy processes

نویسنده

چکیده

We give three applications of the Pecherskii-Rogozin-Spitzer identity for Lévy processes: • Phase-type upward jumps: we find the joint distribution of the supremum and the epoch at which it is ‘attained’ if a Lévy process has phase-type upward jumps. We also find the characteristics of the ladder process. • Perturbed risk models: we establish general properties, and obtain explicit fluctuation identities in case the Lévy process is spectrally positive. • Asymptotics for Lévy processes: we study the tail distribution of the supremum under different assumptions on the tail of the Lévy measure.

Wiener-Hopf factorization for Lévy processes having negative jumps with rational transforms

We give the closed form of the ruin probability for a Lévy processes, possibly killed at a constant rate, with completely arbitrary positive distributed jumps, and finite intensity negative jumps with distribution characterized by having a rational Laplace or Fourier transform. Abbreviated Title: WH-factors of Lévy processes with rational jumps.

Word Embeddings via Tensor Factorization

Most popular word embedding techniques involve implicit or explicit factorization of a word co-occurrence based matrix into low rank factors. In this paper, we aim to generalize this trend by using numerical methods to factor higher-order word co-occurrence based arrays, or tensors. We present four word embeddings using tensor factorization and analyze their advantages and disadvantages. One of...

$n$-factorization Property of Bilinear Mappings

In this paper, we define a new concept of factorization for a bounded bilinear mapping $f:Xtimes Yto Z$, depended on  a natural number $n$ and a cardinal number $kappa$; which is called $n$-factorization property of level $kappa$. Then we study the relation between $n$-factorization property of  level $kappa$ for $X^*$ with respect to $f$ and automatically boundedness and $w^*$-$w^*$-continuity...

Wiener-Hopf factorization for a family of Lévy processes related to theta functions

In this paper we study the Wiener–Hopf factorization for a class of Lévy processes with double-sided jumps, characterized by the fact that the density of the Lévymeasure is given by an infinite series of exponential functions with positive coefficients. We express the Wiener–Hopf factors as infinite products over roots of a certain transcendental equation, and provide a series representation fo...

Special, conjugate and complete scale functions for spectrally negative Lévy processes

Following recent developments in Hubalek and Kyprianou [28] the objective of this paper is to provide further methods for constructing new families of scale functions for spectrally negative Lévy processes which are completely explicit. This will follow as a consequence of an observation in the aforementioned paper which permits feeding the theory of Bernstein functions directly into the Wiener...
