SUMMARY:CCMA Luncheon Seminar - Optimal transport theory\, with some applic
ations
DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Optimal transport theory
\, with some applications\nSpeaker: Alessio Figalli\, University of Texas
at Austin\nAbstract Link: http://www.ma.utexas.edu/users/figalli\nAbstract
: The optimal transportation problem consists in finding the cheapest way
to transport a\ndistribution of mass from one place to another. Surprising
ly\, optimal transportation has become a very powerful tool to obtain shar
p geometric inequalities\, such as for instance the isoperimetric or the B
runn-Minknowski inequality.\nIn this short talk I’ll introduce the optim
al transport problem and show how it can be used to prove this kind of ine
qualities.

SUMMARY:CCMA Luncheon Seminar - Diffusion Maps for data-driven dimensionali
ty reduction
DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Diffusion Maps for data-
driven dimensionality reduction\nSpeaker: Tyrus Berry\, Penn State Univers
ity\nAbstract: Diffusion Maps is an algorithm for finding and describing l
ow-dimensional structure in high-dimensional data based on concepts from R
iemannian geometry. Diffusion Maps relies on a geometric prior which assu
mes that the data set lies `near' a low-dimensional smooth manifold embedd
ed in a high-dimensional Euclidean space. A theoretical result of Coifman
and Lafon shows that\, using only the data and with no other prior inform
ation about the manifold structure\, the Diffusion Maps construction conve
rges to the Laplace-Beltrami operator on the manifold in the limit of larg
e data. Since the Laplace-Beltrami operator determines the Riemannian met
ric\, the Diffusion Maps algorithm captures all aspects of the geometry in
the limit of large data. In this talk I give a comprehensive overview of
Diffusion Maps including an explanation of the algorithm along with visua
lizations and explanations of the intuition behind the steps. I will also
review the key theoretical results and some applications as time permits.

SUMMARY:CCMA Luncheon Seminar - Discretization of PDEs on evolving interfac
es
DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Discretization of PDEs o
n evolving interfaces\nSpeaker: Arnold Reusken\, INSTITUT FÜR GEOMETRIE U
ND PRAKTISCHE MATHEMATIK\nAbstract Link: http://www.igpm.rwth-aachen.de/pe
rsonen/reusken\nAbstract: We consider a \now problem with two dierent imm
iscible incompressible newto-\nnian phases (\nuid-\nuid or \nuid-gas). In
many applications so-called surfactants\nplay an important role. These att
ach to the interface and are transported\, due\nto diusion and convection
\, on the evolving interface. This surfactant trans-\nport can be modeled
by a convection-diusion equation on the surface. In this\ntalk we present
a nite element method for the discretization of the surfactant\nequation
on the evolving interface.

SUMMARY:CCMA Luncheon Seminar - Got PDEs to solve? Try the open source comp

DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Got PDEs to solve? Try t
he open source computational physics platform OpenFOAM\nSpeaker: Xiaofeng
Liu\, Department of Civil and Environmental Engineering\, PSU\nAbstract Li
nk: http://water.engr.psu.edu/liu/\nAbstract: The talk will showcase some
modeling work for various physics problems (mainly in fluid mechanics) usi
ng the open source computational physics platform OpenFOAM®. It has been
more than ten years since OpenFOAM® entered the public domain. The user b
ase has grown tremendously evidenced by the active online community and th
e increasing publications. This platform is essentially a computational to
olbox which solves mathematical models (partial differential equations\, P
DEs) using finite volume method. OpenFOAM solves the PDEs in an automatic
fashion and yet provides sufficient user controls on almost all aspects of
the numerics\, for example discretization schemes. Parallel computation b
ased on domain decomposition is also automatic since the mechanism is buil
t into the lower level of the code structure. Upper level users do not nee
d to know the details. It liberates the researchers from the burden of ext
ensive computer coding and makes it possible for them to focus on the phys
ics. From the abstraction of physical processes to mathematical models\, t
o implement them in OpenFOAM and see the results\, a proficient user proba
bly only needs several hours. Our research group has used it for a variety
of problems\, including river and coastal hydraulics\, porous media flows
\, sedimentation\, buoyant plumes\, etc.

DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Applications of homotopy
method to differential equation\nSpeaker: Wenrui Hao\, Ohio State Univers
ity\nAbstract Link: http://people.mbi.ohio-state.edu/hao.50/\nAbstract: Th
is talk will cover some recent progress on numerical methods to solve syst
ems of nonlinear partial differential equations\n(PDEs) arising from biolo
gy and physics. This new approach\, which is used to compute multiple solu
tions and bifurcation\nof nonlinear PDEs\, makes use of polynomial systems
(with thousands of variables) arising by discretization. Examples\nfrom b
iological models will be used to demonstrate the ideas.

SUMMARY:CCMA Luncheon Seminar - Variational Principles and Sparsity in Imag
ing\, Compressed Sensing and PDEs
DESCRIPTION:Seminar: CCMA Luncheon Seminar\nTitle: Variational Principles a
nd Sparsity in Imaging\, Compressed Sensing and PDEs\nSpeaker: Russel Cafl
isch\, University of California\, Los Angeles\nAbstract Link: http://www.m
ath.ucla.edu/~caflisch/\nAbstract: Variational principles are powerful met
hods for generating the equations of physics\, as well as other fields suc
h as statistics and approximation theory. Constraints and penalization ter
ms in variational principles provide a mechanism for enforcing desirable p
roperties of the solution\, such as conservation laws and smoothness. This
talk will describe the derivation of PDEs from variational principles and
from gradient descent of variational quantities. It will then focus on th
e use of variational principles for image processing\, compressed sensing
and physics. Penalization terms will be used to control noise\, extract in
formation\, and promote sparsity.
