Topology optimization in Bernoulli free boundary problems
Topology optimization Bernoulli free boundary problems
font style='font-size:12px;'>
2011/1/19
In this work we consider topology optimization of systems, which are governed by the external
Bernoulli free boundary problem. We utilize the so-called pseudo-solid approach to solve the
governing f...
Plurisubharmonic and holomorphic functions relative to the plurifine topology
Plurisubharmonic and holomorphic functions the plurifine topology

2010/11/23
A weak and a strong concept of plurifinely plurisubharmonic and plurifinely holomorphic functions are introduced. Strong will imply weak. The weak concept is studied further. A function f is weakly pl...
Symmetry breaking: A tool to unveil the topology of chaotic scattering with three degrees of freedom
Chaotic Dynamics (nlin.CD)

2010/11/10
We shall use symmetry breaking as a tool to attack the problem of identifying the topology of chaotic scatteruing with more then two degrees of freedom. specifically we discuss the structure of the ho...

We use the "pearl" machinery in our previous work to study certain enumerative invariants associated to monotone Lagrangian submanifolds.
Measuring Shape with Topology
Measuring Shape Topology math

2010/11/15
We propose a measure of shape which is appropriate for the study of a complicated geometric structure, defined using the topology of neighborhoods of the structure. One aspect of this measure gives a...

In this paper we study the relationship between the moment-angle complex Z_k and the Davis-Januskiewicz space DJ(K) for a class of complexes K named missing-face complexes. If K has n vertices we con...
Search for neutral Higgs bosons in the multi-b-jet topology in 5.2fb-1 of ppbar collisions at sqrt(s)=1.96 TeV
Search for neutral Higgs bosons multi-b-jet topology 5.2fb-1 of ppbar collisions

2011/1/4
Data recorded by the D0 experiment at the Fermilab Tevatron Collider are analyzed to search
for neutral Higgs bosons produced in association with b quarks.
Magnetic Topology of Coronal Hole Linkages
magnetic topology—Sun corona—Sun solar wind—Sun NASA/GSFC
font style='font-size:12px;'>
2010/11/9
In recent work, Antiochos and coworkers argued that the boundary between the open and closed field regions on the Sun can be extremely complex with narrow corridors of open flux connecting seemingly d...

Topology subsets - the story of a theorem
font style='font-size:12px;'>
2010/11/11
In this exposition the space of at most 3-element subsets of the circle, first identified by Borsuk and Bott, is used as a motivation to introduce the readers to a variety of methods in (algebraic) to...
Homologous Flares and Magnetic Field Topology in Active Region NOAA 10501 on 20 November 2003
Active Regions Magnetic Fields Flares Dynamics Flares Relation
font style='font-size:12px;'>
2010/11/11
We present and interpret observations of two morphologically homologous flares that occurred in active region (AR) NOAA 10501 on 20 November 2003. Both flares displayed four homologous H ribbons and ...

Topology of large scale structure as test of modified gravity
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
font style='font-size:12px;'>
2011/1/5
The genus of the iso-density contours is a robust measure of the topology of large-scale structure, and relatively insensitive to galaxies biasing and redshift-space distortions. We show that the grow...

2010/12/14
We study locally compact group topologies on simple Lie groups. We show that the Lie group topology on such a group S is very rigid: every ’abstract’ isomorphism between S and a locally compact and -...

The first part of this paper provides a new formulation of chiral differential operators (CDOs) in terms of global geometric quantities. The main result is a recipe to define essentially all sheaves o...

For each k > 0 we find an explicit function fk such that the topology of S inside the ball
BS(p, r) is ‘bounded’ by fk(r) for every complete Riemannian surface (compact or noncompact) S with K W...
