SUMMARY:On the monotonicity of the speed of biased random walk on a Galton
 -Watson tree without leaves - Alexander Fribergh (Courant Institute of Mat
 hematical Sciences)

DESCRIPTION:We will present different results related to the speed of bias
 ed random\nwalks in random environments. Our main focus will be on a recen
 t paper (by Ben Arous\,\nFribergh and Sidoravicius) proving that the speed
  of the biased random walk on a\nGalton-Watson tree without leaves is incr
 easing for high biases. This partially\naddresses a question asked by Lyon
 s\, Pemantle and Peres.
