Stochastic differential equation with jumps for multi-type continuous state and continuous time branching processes with immigration
TL;DR: In this paper, a multi-type continuous state and continuous time branching process with immigration satisfying some moment conditions is identified as a pathwise unique strong solution of certain stochastic dierential equation with jumps.

Asymptotic behavior of unstable INAR(p) processes
TL;DR: In this paper, the asymptotic behavior of an unstable integer-valued autoregressive model of order p (INAR( p )) is described and it is proved that the sequence of appropriately scaled random step functions formed from an unstable INAR(p ) process converges weakly towards a squared Bessel process.

Yamada-Watanabe Results for Stochastic Differential Equations with Jumps
TL;DR: In this paper, a general version of the Yamada-Watanabe and Engelbert theorems relating existence and uniqueness of weak and strong solutions of stochastic equations with jumps was presented.

Stationarity and ergodicity for an affine two-factor model
TL;DR: In this article, the existence of a unique stationary distribution and ergodicity for a two-dimensional affine process with α ∈ (1, 2) and α = 2 was studied.

Stationarity and ergodicity for an affine two factor model
TL;DR: In this article, the existence of a unique stationary distribution and ergodicity for a 2-dimensional affine process with alpha-root process was proved in case of α = 2 and α = 1.
