On some inequalities relative to the Pompeiu–Chebyshev functional
Journal of Inequalities and Applications, 2020 In this paper we study the utility of the functional Pompeiu–Chebyshev in some inequalities. Some results obtained by Alomari will be generalized regarding inequalities with Pompeiu–Chebyshev type functionals, in which linear and positive functionals ...

Valuing American Put Options Using Chebyshev Polynomial Approximation [PDF]
, 2005 This paper suggests a simple valuation method based on Chebyshev approximation at Chebyshev nodes to value American put options. It is similar to the approach taken in Sullivan (2000), where the option`s continuation region function is estimated by using
