Symbolic approach to the general quadratic polynomial decomposition
Ângela Macedo, Teresa Mesquita, Zélia da Rocha
In this work we deal with a symbolic approach to the general quadratic polynomial decomposition. By means of a symbolic implementation, we investigate some properties of the compon…

On connection coefficients, zeros and interception points of some perturbed of arbitrary order of the Chebyshev polynomials of second kind
Zélia da Rocha
Orthogonal polynomials satisfy a recurrence relation of order two, where appear two coefficients. If we modify one of these coefficients at a certain order, we obtain a perturbed o…
