The aim of this thesis is to find the lower and upper bounds of the constant whichappears in the Markov Bernstein inequalities in L2 norm associated to the Jacobiand generalized Gegenbauer measures. In this work the qd algorithm is studied forobtaini

In the present paper the authors make an attempt to give a uniform description of the main properties of tridiagonal, band, block tridiagonal and block band matrices and their inverses. Some basic concepts are recalled and also some new results are p
