SUMMARY:Of crystals and corals
LOCATION:Zoom
DESCRIPTION:<p>Abstract: There are many real-world processes exhibiting fractal growing
  shapes - from mineral deposition and coral growth to lightning strikes, an
 d in many of them growth is related to diffusion properties. We will discus
 s two seminal models: Diffusion Limited Aggregation was introduced by Witte
 n and Sanders in 1981 and was generalized to Dielectric Breakdown Model by 
 Niemayer et al shortly afterwards. Numerically they approximate very well a
  wide range of physical phenomena. However, despite a very simple definitio
 n (DLA cluster grows by attaching particles undergoing Brownian motion when
  they hit the aggregate), very little is understood today, and even less is
  known rigorously - essentially, only the famous Harry Kesten upper bound o
 n the DLA growth.</p><p>We will try to show the flavor of these models and&
 nbsp; present some new results.</p>
