It offers original textbook-level material suitable for introductory or advanced courses as well as deep insights into the state of the art of the field, making it useful as a reference and for self-study.  The first chapters introduce hyperbolic dynamics, ergodic theory and geodesic and horocycle flows, and include an English translation of Hadamard's original proof of the Stable-Manifold Theorem. An outline of the strategy, motivation and context behind the ergodicity proof is followed by a careful exposition of it (using the Hopf argument) and of the pertinent context of Teichmüller theory. Finally, some complementary lectures describe the deep connections between geodesic flows in negative curvature and Diophantine approximation 650 0$aErgodic theory$vCongresses 650 0$aDynamics 700 1 $aHasselblatt, Boris 776 08$iPrinted edition:$z9783319430584 856 40$uhttps://link.springer.com/book/10.1007/978-3-319-43059-1$zAn electronic book accessible through the World Wide 907 $a.b14354020$b03-03-22$c22-11-18 912 $a991003575059707536 996 $aErgodic theory and negative curvature$91522941 997 $aUNISALENTO 998 $ale013$b22-11-18$cm$d@ $e-$feng$gsz $h0$i0 LEADER 01905nam 2200577 450 001 9910827857603321 005 20180731044357.0 010 $a1-4704-0188-6 035 $a(CKB)3360000000464787 035 $a(EBL)3114579 035 $a(SSID)ssj0000888920 035 $a(PQKBManifestationID)11465746 035 $a(PQKBTitleCode)TC0000888920 035 $a(PQKBWorkID)10866271 035 $a(PQKB)10993306 035 $a(MiAaPQ)EBC3114579 035 $a(RPAM)2108010 035 $a(PPN)195414861 035 $a(EXLCZ)993360000000464787 100 $a19961105h19971997 uy| 0 101 0 $aeng 135 $aur|n|---||||| 181 $ctxt 182 $cc 183 $acr 200 10$aExtended affine Lie algebras and their root systems /$fBruce N.
