On character of points in the Higson corona of a metric space
Higson corona character of a point ultrafilter number dominating number
2012/6/19
We prove that for an unbounded metric space $X$, the minimal character $m\chi(\check X)$ of a point of the Higson corona $\check X$ of $X$ is equal to $\mathfrak u$ if $X$ has asymptotically isolated ...
Coloring, location and domination of corona graphs
Coloring domination location Roman domination corona graphs
2012/4/18
A vertex coloring of a graph $G$ is an assignment of colors to the vertices of $G$ such that every two adjacent vertices of $G$ have different colors. A coloring related property of a graphs is also a...
On the strong metric dimension of corona product graphs and join graphs
Strong metric dimension strong resolving sets strong metric basis clique number corona graph
2012/4/18
Let $G$ be a connected graph. A vertex $w$ strongly resolves a pair $u$, $v$ of vertices of $G$ if there exists some shortest $u-w$ path containing $v$ or some shortest $v-w$ path containing $u$. A se...
Cyclicity of singular inner functions from the corona theorem
Weighted Bergman space cyclic function singular inner function
2011/2/28
Carleson’s corona theorem is used to obtain two results on cyclicity of singular inner functions in weighted Bergman-type spaces on the unit disk. Our method proof requires no regularity conditions on...
Strong [O III] and [N II] emission lines in globular clusters from photoionized R Corona Borealis star winds
emission lines globular clusters
2011/1/13
The globular cluster X-ray source CXO J033831.8-352604 in NGC 1399 has recently been found to show strong emission lines of [O III] and [N II] in its optical spectrum in addition to ultraluminous X-ra...
On the metric dimension of corona product graphs
Resolving sets metric dimension corona graph
2010/12/6
Given a set of vertices S = {v1, v2, ..., vk} of a connected graph G, the metric representation of a vertex v of G with respect to S is the vector r(v|S) = (d(v, v1), d(v, v2), ..., d(v, vk )), where ...
Spectroscopic Studies of Solar Corona VI: Trend in Line-width Variation of Coronal Emission Lines with Height Independent of the Structure of Coronal Loops
Sun corona coronal structures emission line widt techniques spectroscopy
2010/9/16
We have obtained spectroscopic observations in coronal emission lines by choosing two lines simultaneously, one [Fe x] 6374Å and the other [Fe xi] 7892Å or [Fe xiii] 10747Å or [Fe xi...
Nanoflares and Heating of the Solar Corona
Sun stars—magnetic reconnection coronal heating—nanoflares
2010/9/16
Coronal heating by nanoflares is presented by using observational,analytical, numerical simulation and statistical results. Numerical simulations show the formation of numerous current sheets if the m...
Proper asymptotic unitary equivalence in $\KK$-theory and projection lifting from the corona algebra
KK-theory proper asymtotic unitary equivalence ab-sorbing representation
2010/12/6
In this paper we generalize the notion of essential codimension of Brown, Douglas, and Fillmore using KK-theory and prove a result which asserts that there is a unitary of the
form ‘identity + compac...
On ion-cyclotron-resonance heating of the corona and solar wind
ion-cyclotron-resonance heating corona solar wind
2009/11/11
This paper concisely summarizes and critically reviews recent work by the authors on models of the heating of the solar corona by resonance of ions with high-frequency waves (up to the proton cyclotro...
MHD turbulence and heating of the open field-line solar corona
MHD turbulence open field-line solar corona
2009/11/11
This paper discusses the possibility that heating of the solar corona in open field-line regions emanating from coronal holes is due to a nonlinear cascade, driven by low-frequency or quasi-static mag...
Intermittent heating of the solar corona by MHD turbulence
Intermittent heating solar corona MHD turbulence
2009/11/3
As the dissipation mechanisms considered for the heating of the solar corona would be sufficiently efficient only in the presence of small scales, turbulence is thought to be a key player in the coron...
Joule heating and anomalous resistivity in the solar corona
Joule heating anomalous resistivity solar corona
2009/10/30
Recent radioastronomical observations of Faraday rotation in the solar corona can be interpreted as evidence for coronal currents, with values as large as 2.5×109 Amperes (Spangler, 2007). These estim...
