PARAMETER CHOICE FOR FAMILIES OF MAPS WITH MANY CRITICAL POINTS
PARAMETER CHOICE MAPS WITH MANY CRITICAL POINTS
2015/9/25
We consider families of smooth one-dimensional maps with several critical points and outline the main ideas of the construction in the parameter space that allows to get infinite Markov Partitions and...
On the Distribution of Critical Points of a Polynomial
Critical Points Polynomial Probability
2012/7/11
This paper proves that if points $Z_1,Z_2,...$ are chosen independently and identically using some measure $\mu$ from the unit circle in the complex plane, with $p_n(z) = (z-Z_1)(z-Z_2)...(z-Z_n)$, th...

Distance function critical points Morse index Cech complex Poisson process central limit theorem Betti numbers
2011/9/20
Abstract: For a finite set of points $P$ in $R^d$, the function $d_P:R^d \to R_+$ measures Euclidean distance to the set $P$. We study the number of critical points of $d_P$ when $P$ is random. In par...
Glueballs in large-N YM by localization on critical points
Glueballs large-N YM critical points High Energy Physics - Theory
2011/10/9
Abstract: By exploiting in large-N YM the change of variables from the gauge connection to the ASD part of its curvature by a non-SUSY version of the Nicolai map, we show that certain twistor Wilson l...
Change point analysis of an exponential model based on Phi-divergence test-statistics: simulated critical points case

2011/8/25
Abstract: Recently Batsidis \textit{et al.} (2011) have presented a new procedure based on divergence measures for testing the hypothesis of the existence of a change point in exponential populations....

2011/9/15
A class of random graphs is introduced and studied. The graphs are constructed in an algorithmic way from five motifs which were found in [Milo R., Shen-Orr S., Itzkovitz S., Kashtan N., Chklovskii D....
Categories of partial algebras for critical points between varieties of algebras
Partial algebra congruence relation gamp pregamp variety of algebras
2011/1/19
We denote by Conc A the (∨, 0)-semilattice of all finitely generated congruences of an algebra A. A lifting of a (∨, 0)-semilattice S is an algebra A such that S ∼=Conc A.
We obtain an upper bound for the derivative of a Blaschke product, whose zeros lie in a certain Stolz-type region. We show that the derivative belongs to the space of analytic functions in the unit di...
Phase space barriers and dividing surfaces in the absence of critical points of the potential energy
Phase space dividing surfaces critical points the potential energy
2010/11/12
We consider the existence of invariant manifolds in phase space governing reaction dynamics in situations where there are no saddle points on the potential energy surface in the relevant regions of co...
Protecting clean critical points by local disorder correlations
Protecting clean critical points local disorder correlations
2010/11/17
We show that a broad class of quantum critical points can be stable against locally correlated
disorder even if they are unstable against uncorrelated disorder. Although this result seemingly contrad...
Entanglement spectrum of random-singlet quantum critical points
Entanglement spectrum random-singlet quantum critical points
2010/10/22
The entanglement spectrum, i.e., the full distribution of Schmidt eigenvalues of the reduced
density matrix, contains more information than the conventional entanglement entropy and has been studied ...
THE PROXIMITIES OF ASTEROIDS AND CRITICAL POINTS OF THE DISTANCE FUNCTION
Celestial mechanics Minor planets asteroids
2010/10/29
The proximities are important for di®erent purposes, for example to evaluate the risk of collisions of asteroids or comets with the Solar-System planets. We describe a simple and e±cient method fo...
Hodograph solutions of the dispersionless coupled KdV hierarchies, critical points and the Euler-Poisson-Darboux equation
Hodograph solutions scalar function Euler-Poisson-Darboux equation
2010/4/2
It is shown that the hodograph solutions of the dispersionless coupled KdV (dcKdV) hierarchies describe critical and degenerate critical points of a scalar function which obeys the Euler-Poisson-Darbo...

Effects of interference dynamics of spin-1/2 transverse XY Chain quantum critical points
2010/4/13
We study the effects of interference on the quenching dynamics of a one-dimensional spin 1/2 $XY$ model in the presence of a transverse field ($h(t)$) which varies sinusoidally with time as $h = h_0\c...
