We study a branching Brownian motion $Z$ in $\mathbb{R}^d$, among obstacles scattered according to a Poisson random measure with a radially decaying intensity. Obstacles are balls with constant radius and each one works as a trap for the whole motion when hit by a particle. Considering a general offspring distribution, we derive the decay rate of the annealed probability that none of the particles of $Z$ hits a trap, asymptotically in time $t$. This proves to be a rich problem motivating the…

Branching Brownian motion in an expanding ball and application to the mild obstacle problem

We first consider a d-dimensional branching Brownian motion (BBM) evolving in an expanding ball, where the particles are killed at the boundary of the ball, and the expansion is subdiffusive in time.

Large deviations for local mass of branching Brownian motion

We study the local mass of a dyadic branching Brownian motion Z evolving in Rd. By ‘local mass,’ we refer to the number of particles of Z that fall inside a ball with fixed radius and time-dependent

The branching Brownian sausage in R was defined in [4] similarly to the classical Wiener sausage, as the random subset of R scooped out by moving balls of fixed radius with centers following the

Maximal displacement and population growth for branching Brownian motions

We study the maximal displacement and related population for a branching Brownian motion in Euclidean space in terms of the principal eigenvalue of an associated Schr\"odinger type operator. We first

Maximum of Branching Brownian Motion among mild obstacles

Asymptotic radial speed of the support of supercritical branching Brownian motion and super-Brownian motion in R^d

It has long been known that the left-most or right-most particle in a one dimensional dyadic branching Brownian motion with constant branching rate β > 0 has almost sure asymptotic speed √ 2β, (cf.

Quenched law of large numbers for branching Brownian motion in a random medium

Escape Probabilities for Branching Brownian Motion Among Soft Obstacles

We derive asymptotics for the quenched probability that a critical branching Brownian motion killed at a small rate ε in Poissonian obstacles exits from a large domain. Results are formulated in

Maximal displacement of branching brownian motion

It is shown that the position of any fixed percentile of the maximal displacement of standard branching Brownian motion in one dimension is 21/2t–3 · 2−3/2 log t + O(1) at time t, the second-order

Branching diffusions, superdiffusions and random media

Spatial branching processes became increasingly popular in the past decades, not only because of their obvious connection to biology, but also because superprocesses are intimately related to

An Application of the Backbone Decomposition to Supercritical Super-Brownian Motion with a Barrier

The behaviour of supercritical super-Brownian motion with a barrier through the pathwise backbone embedding of Berestycki et al.
