SUMMARY:Ph.D. Oral Comprehensive Examination - "Fibrations of Euclidean Spa
ce by Skew Flat Fibers"
DESCRIPTION:Seminar: Ph.D. Oral Comprehensive Examination\nTitle: "Fibratio
ns of Euclidean Space by Skew Flat Fibers"\nSpeaker: Mike Harrison\, Advis
er: Sergei Tabachnikov/Kris Wysocki\, Penn State\nAbstract Link: http://
\nAbstract: Two copies of R^p are called skew if they neither intersect no
r contain parallel directions. We discuss a recent result of Ovsienko and
Tabachnikov which gives conditions on p and n for the existence of a fibr
ation of R^n by pairwise skew\, oriented copies of R^p. We then provide s
ome positive results in the direction of classifying skew fibrations\, inc
luding a slight generalization of Salvai's recent characterization of smoo
th\, skew fibrations in the case where n=3 and p=1. To conclude\, we exa
mine the relationship between spherical fibrations and flat fibrations\, a
nd we offer a number of avenues for further study in this area.

SUMMARY:Ph.D. Oral Comprehensive Examination - "On local structure of Finsl
er torus without conjugate points"
DESCRIPTION:Seminar: Ph.D. Oral Comprehensive Examination\nTitle: "On local
structure of Finsler torus without conjugate points"\nSpeaker: Dong Chen
\, Adviser: Dima Burago\, Penn State\nAbstract Link: http://\nAbstract: I
n 1994 Burago and Ivanov proved Hopf’s conjecture\, that is\, Riemannian
tori without conjugate points are flat. However\, this conjecture does no
t hold in Finsler cases. \nWe proved\, given a point on a Finsler surface
\, one can always find a neighborhood of the point and isometrically embed
this neighborhood into a Finsler torus without conjugate points. In order
to prove this we need to extend the notion of Busemann functions and make
some perturbation and extension of such functions. And we offer some futu
re open problems to work on.

SUMMARY:Ph.D. Oral Comprehensive Examination - "A peridynamic Formulation f
or Phase Transformation"
DESCRIPTION:Seminar: Ph.D. Oral Comprehensive Examination\nTitle: "A peridy
namic Formulation for Phase Transformation"\nSpeaker: Liming Yuan\, Advise
r: Qiang Du\, Penn State\nAbstract Link: http://\nAbstract: Phase transfo
rmation in solids has drawn much attention since 1970s\, which also contri
butes to the study of the system of conservation law. Recently a peridynam
ic formulation for elastic problems is proposed. In this ongoing project\,
we target to explore the phenomenon from peridynamic point of view\, focu
sing on the similarities and distinctions to the classical theory.

DESCRIPTION:Seminar: Ph.D. Oral Comprehensive Examination\nTitle: "Uniquene
ss of conservative weak solution to Camassa-Holm equation via characterist
ics"\nSpeaker: Qingtian Zhang\, Adviser: Alberto Bressan\, Penn State\nAb
stract: Camassa-Holm equation is an approximate model to describe water wa
ves. In this talk\, I will introduce some classical results of Camassa-Hol
m equation\, and present our recent result concerning the uniqueness of co
nservative solution to Camassa-Holm equation. This is a joint work with Al
berto Bressan and Geng Chen.

SUMMARY:Ph.D. Oral Comprehensive Examination - "Covering Dimension for Nucl
ear C*-algebras"
DESCRIPTION:Seminar: Ph.D. Oral Comprehensive Examination\nTitle: "Covering
Dimension for Nuclear C*-algebras"\nSpeaker: Hung-Chang Liao\, Adviser:
Nate Brown\, Penn State\nAbstract: The classical covering dimension of a t
opological space can be \ndefined through a certain decomposability of op
en coverings. The \nnoncommutative version (for nuclear C*-algebras) is de
fined in terms of \nuniformly decomposable completely positive approximati
ons. In this talk\, \nI will begin with some background in approximation p
roperties related to \nnuclear C*-algebras\, and then discuss the connecti
on between nuclearity \nand dimension of topological spaces.
