SUMMARY:Center for Dynamics and Geometry Colloquium - A survey of C^1 gener
ic ergodic theory
DESCRIPTION:Seminar: Center for Dynamics and Geometry Colloquium\nTitle: A
survey of C^1 generic ergodic theory\nSpeaker: Jairo Bochi\, Pontifical Un
iversity of Chile\nAbstract: I'll survey what is known about the ergodic t
heory of C^1-generic conservative diffeomorphisms\, culminating with the f
ollowing theorem of Avila\, Crovisier\, and Wilkinson: C^1-generic volume-
preserving diffeomorphisms either have zero metric entropy or are ergodic
and ``semi-uniformly Anosov''. I'll explain informally the main ideas used
in the proofs.

SUMMARY:Center for Dynamics and Geometry Colloquium - Fractal curvatures an
d dynamical systems
DESCRIPTION:Seminar: Center for Dynamics and Geometry Colloquium\nTitle: Fr
actal curvatures and dynamical systems\nSpeaker: Martina Zaehle\, Friedric
h Schiller University\, Jena\, Germany\nAbstract: In the first part of the
talk we give an introduction to local and global curvature notions for so
me classes of fractals via approximation by Euclidean neighborhoods. The M
inkowski content is included. Then we briefly explain how the correspondin
g problem of convergence of the rescaled Lipschitz-Killing curvatures of
parallel sets can be treated with the help of embedded dynamical systems
and renewal theory. We also discuss the interplay between both approaches.

SUMMARY:Center for Dynamics and Geometry Colloquium - Equidistribution of s
tretching translates of curves on homogeneous spaces
DESCRIPTION:Seminar: Center for Dynamics and Geometry Colloquium\nTitle: Eq
uidistribution of stretching translates of curves on homogeneous spaces\nS
peaker: Nimish Shah\, Ohio State University\nAbstract: We consider a finit
e piece C of an analytic curve on a minimal expanding (abelian) horospheri
cal subgroup of G=SL(n\,R) associated to a certain diagonal element g in G
. We consider the subgroup action of G on a finite volume homogeneous spac
e X\, and consider the trajectory of C from some point x in X. We want to
understand algebraic conditions on C which ensure that in the limit\, the
translates of the curve Cx by g^n get equidistributed in the (homogeneous)
closure of the G-orbit of x as 𝑛→∞. In this talk we describe some
recent joint work with Lei Yang on this problem. \n\nSuch results have ap
plications to metric properties of Diophantine approximation\; for example
\, to show non-improvability of Dirichlet’s approximation on curves in t
he space of matrices.

SUMMARY:Center for Dynamics and Geometry Colloquium - Uniform distribution
\, generalized polynomials\, translations on nil-manifolds and Ramsey theo
ry
DESCRIPTION:Seminar: Center for Dynamics and Geometry Colloquium\nTitle: Un
iform distribution\, generalized polynomials\, translations on nil-manifol
ds and Ramsey theory\nSpeaker: Vitaly Bergelson\, Ohio State University\nA
bstract: A classical theorem due to H. Weyl states that if P is a real pol
ynomial such that at least one of its coefficients (other than the constan
t term) is irrational\, then the sequence P(n)\, n=1\,2\,... is uniformly
distributed mod 1. After briefly reviewing various approaches to the proof
of Weyl's theorem\, we will discuss some recent extensions which involve
"generalized polynomials"\, that is\, functions which are obtained from th
e conventional polynomials by the use of the greatest integer function\, a
ddition and multiplication. We will explain the role of dynamical systems
on nil-manifolds in obtaining these results and discuss the intrinsic conn
ection between the generalized polynomials and the polynomial extensions o
f Szemeredi's theorem on arithmetic progressions. We will also discuss the
recent joint work with Leibman on characterization of nil-translations in
terms of recurrence. We will conclude with formulating and discussing som
e natural open problems and conjectures.
