DESCRIPTION:Speakers: Wolf JUNG\n\nQuadratic Thurston maps are postcritica
lly finite branched coverings\, which may be equivalent to a rational map
or not. The talk focuses on maps with four postcritical points\, that are
covered by a real affine map on a lattice. So\, many questions from comple
x dynamics are solved explicitly by linear algebra\, including:Is the map
equivalent to a rational map?How about essential matings from non-conjugat
e limbs?When are two Thurston maps equivalent?What is the effect of a Dehn
twist?Are preimages of an essential curve eventually periodic?Is the virt
ual endomorphism of the pure mapping class group contracting? \n\nhttps:/
