Quantifying non-monotonicity of functions and the lack of positivity in signed measures
Modern Stochastics: Theory and Applications, 2017 In various research areas related to decision making, problems and their solutions frequently rely on certain functions being monotonic. In the case of non-monotonic functions, one would then wish to quantify their lack of monotonicity.

A Comparison of Papoulis and Chebyshev Filters in the Continuous Time Domain [PDF]
Radioengineering, 2021 The subject of this paper is the revisit of the Chebyshev (equiripple) and Papoulis (monotonic or staircase) low-pass filter in order to compare. It can be stated the fair comparison of Papoulis and Chebyshev filters cannot be found in the available ...

Recurrence relations for Chebyshev-type methods. [PDF]
, 2000 The convergence of new second-order iterative methods are analyzed in Banach spaces by introducing a system of recurrence relations. A system of a priori error bounds for that method is also provided.
