We obtain complementary recurrence and transience criteria for processes $X=(X_n)_{n \ge 0}$ with values in $\mathbb R^d_+$ fulfilling a non-linear equation $X_{n+1}=MX_n+g(X_n)+ \xi_{n+1}$. Here $M$ denotes a primitive matrix having Perron-Frobenius eigenvalue 1, and $g$ denotes some function. The conditional expectation and variance of the noise $(\xi_{n+1})_{n \ge 0}$ are such that $X$ obeys a weak form of the Markov property. The results generalize criteria for the 1-dimensional case in [5…

Recurrence and Transience of Near-Critical Multivariate Growth Models: Criteria and Examples
We consider stochastic processes (X n )n ≥ 0 taking values in \(\mathbb{R}_{+}^{d} =\{ (x_{1},\ldots,x_{d})^{T} \in \mathbb{R}^{d}: x_{i} \geq 0\}\), i.e. the d-dimensional orthant, and adapted to
On recurrence and transience of growth models
Let Xn be non-negative random variables, possessing the Markov property. We given criteria for deciding whether Pr(X. -- oo) is positive or 0. It turns out that essentially this depends on the
