The degree sequence $(N_{i,j}(k),1\leq i,j\leq d,k\geq 0)$ of a multitype forest with $d$ types, is the number of individuals type $i$, having $k$ children type $j$. We construct a multitype forest sampled uniformly from all multitype forest with a g

Random walks conditioned to stay positive are a prominent topic in fluctuation theory. One way to construct them is as a random walk conditioned to stay positive up to time $n$, and let $n$ tend to infinity. A second method is conditioning instead to

Let $X$ be an exchangeable increment (EI) process whose sample paths are of infinite variation. We prove that, for any fixed $t$ almost surely, \[ \limsup_{h\to 0 \pm} (X_{t+h}-X_t)/h=\infty \quad\text{and}\quad \liminf_{h\to 0\pm} (X_{t+h}-X_t)/h=-\
