A modified least squares method: Approximations on the unit circle and on (−1,1)
The main objective in the present manuscript is to consider approximations of functions defined on the unit circle by Laurent polynomials derived from certain combinations of kernel polynomials of orthogonal polynomials ...
Sobolev Orthogonal Polynomials on the Unit Circle and Coherent Pairs of Measures of the Second Kind
We refer to a pair of non trivial probability measures (μ0, μ1) supported on the unit circle as a coherent pair of measures of the second kind on the unit circle if the corresponding sequences of monic orthogonal polynomials ...
Coordination dynamics and attentional costs of continuous and discontinuous bimanual circle drawing movements
(ELSEVIER SCIENCE BV, 2008)
It has been suggested that the temporal control of rhythmic unimianual movements is different between tasks requiring continuous (e.g., circle drawing) and discontinuous movements (e.g., finger tapping). Specifically, for ...
CLASSROOM CIRCLE AS ACTIVITY FOR MAKING EASIER THE DEVELOPMENT OF MORAL JUDGMENT FROM CHILDREN'S EDUCATION
(Univ Estadual Parana, Escola Musica & Belas Artes Parana, 2016-01-01)
The research presented has the main objective of studying the classroom circle as a permanent activity able to develop the moral judgment of the children, when performed in a planned way, with clear objectives and interventions ...
Orthogonal polynomials with respect to a family of Sobolev inner products on the unit circle
The principal objective here is to look at some algebraic properties of the orthogonal polynomials Ψn (b,s,t) n with respect to the Sobolev inner product on the unit circle <f,g>S (b,s,t) = (1 − t) <f,g>μ(b) + t f(1) g(1) ...
Structural results on circular-arc graphs and circle graphs: a survey and the main open problems
(Elsevier Science, 2014-02)
Circular-arc graphs are the intersection graphs of open arcs on a circle. Circle graphs are the intersection graphs of chords on a circle. These graph classes have been the subject of much study for many years and numerous ...
Quadrature rules from a R I I type recurrence relation and associated quadrature rules on the unit circle
We consider the theoretical and numerical aspects of the quadrature rules associated with a sequence of polynomials generated by a special R II recurrence relation. We also look into some methods for generating the nodes ...
Sieved para-orthogonal polynomials on the unit circle
(Elsevier B.V., 2014-10-01)
Sieved orthogonal polynomials on the unit circle were introduced independently by Ismail and Li (1992)  and Marcellan and Sansigre (1991) . We look at the para-orthogonal polynomials, chain sequences and quadrature ...

Decay of geometry for Fibonacci critical covering maps of the circle
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2009)
We study the growth of Df `` (f(c)) when f is a Fibonacci critical covering map of the circle with negative Schwarzian derivative, degree d >= 2 and critical point c of order l > 1. As an application we prove that f exhibits ...
