SUMMARY:Ph.D. Thesis Defense - “Studies on the weak convergence of partia
l sums in Gibbs-Markov dynamical systems”
DESCRIPTION:Seminar: Ph.D. Thesis Defense\nTitle: “Studies on the weak co
nvergence of partial sums in Gibbs-Markov dynamical systems”\nSpeaker: X
uan Zhang\, Adviser: Manfred Denker\, Penn State\nAbstract: We investigat
es distributional limit theorems of partial sums of the form $f_{n\,1}+f_{
n\,2}\\circ T_n+\\cdots+f_{n\,n}\\circ T_n^{n-1}$ for Gibbs-Markov dynamic
al systems $(X_n\, \\mathscr B_n\, T_n\,\\mu_n\,\\alpha_n)$ and an array o
f functions $f_{n\,m}: X_n\\to \\mathbb R$ of certain classes. We show a C
entral Limit Theorem (CLT) for this array\, a CLT of Lindeberg type (with
uniformly bounded functions) and we also investigate the Poisson limit cas
e. We relate the Poisson limit theorem to escape rates of sweep-out sets a
nd the CLT is applied in various situations\, in particular to some statis
tical functions.

SUMMARY:Ph.D. Thesis Defense - " A Complete Set of Invariants for Density O
perators Under Local Conjugation"
DESCRIPTION:Seminar: Ph.D. Thesis Defense\nTitle: " A Complete Set of Invar
iants for Density Operators Under Local Conjugation"\nSpeaker: Jacob Turne
r\, Adviser: Jason Morton\, Penn State\nAbstract: A density operator of i
s a trace one\, positive semi-definite matrix in the tensor product of the
spaces End (V_i) for i=1\,...\,n. These are used in physics to represent
a quantum system of n particles\, the ith of which has dim (V_i) spins. On
e of the most important questions about a density operator is the entangle
ment of the state it represents. Almost every notion of entanglement is in
variant under conjuagation by the affine cone over the Segre product of th
e unitary groups over each V_i. Using techniques from algebraic geometry a
nd representation theory\, we determine a finite set of invariant polynomi
als that completely seperate orbits of density operators.

SUMMARY:Ph.D. Thesis Defense - "Rokhlin Dimension for C*-Correspondences"
DESCRIPTION:Seminar: Ph.D. Thesis Defense\nTitle: "Rokhlin Dimension for C*
-Correspondences"\nSpeaker: Aleksey Zelenberg\, Adviser: Nate Brown\, Pen
n State\nAbstract: The notion of nuclear dimension for C*-algebras was def
ined by Winter and Zacharias as a noncommutative analog of covering dimens
ion for topological spaces. In recent years nuclear dimension has generate
d a great deal of interest\, not only due to its connection to other struc
tural properties such as Jiang-Su stability and strict comparison\, but al
so because it seems to be a unifying principle in the classification progr
am of nuclear C*-algebras using K-theoretic invariants. As such\, much wor
k as been done to understand how nuclear dimension behaves for various con
structions. Along these lines\, Hirshberg\, Winter\, and Zacharias proved
that if A is a C*-algebra being acted on by an automorphism having finite
Rokhlin dimension\, then the associated crossed product has finite nuclear
dimension whenever A does. This talk will outline how to generalize this
result. Indeed\, since a crossed product by the integers can be regarded a
s a Cuntz-Pimsner algebra associated to a singly-generated C*-corresponden
ce\, we propose a definition of Rokhlin dimension for arbitrary correspond
ences that agrees with the traditional one in the singly-generated case. W
e will then show that in many cases (such as for finitely generated projec
tive modules)\, finiteness of nuclear dimension for Pimsner algebras is pr
eserved in the presence of finite Rokhlin dimension. If time permits\, we
will outline how these results imply that certain types of amalgamated fre
e products have finite nuclear dimension.

SUMMARY:Ph.D. Thesis Defense - "Hyperelliptic Jacobians and their associate
d \\ell-adic Galois representations"
DESCRIPTION:Seminar: Ph.D. Thesis Defense\nTitle: "Hyperelliptic Jacobians
and their associated \\ell-adic Galois representations"\nSpeaker: Jeff Yel
ton\, Adviser: Yuri Zarhin\, Penn State\nAbstract Link: http://\nAbstract
: Let k be a subfield of the complex numbers\, and let K be the extension
of k obtained by adjoining the symmetric functions of the independent tran
scendental elements \\alpha_{1}\, \\alpha_{2}\, ... \, \\alpha_{d} for som
e d at least 3. We are interested in action of the absolute Galois group
of K on the \\ell-adic Tate modules of the Jacobian J of the "generic" deg
ree-d hyperelliptic curve C whose Weierstrass roots are the \\alpha_{i}'s
\, in particular when \\ell = 2. I will begin by describing of the image
of the absolute Galois group under the induced \\ell-adic representation\,
as well as the main topological argument used to prove this result. It w
ill be shown how this method can further be used to derive generators for
the field extensions over which the points in certain torsion 2-subgroups
are defined. I will also describe how to use sequences of isogenies to gi
ve a full desription of the infinite algebraic extension of K generated by
the coordinates of all 2-power torsion points of J when when the genus is
1 or 2.
