Normalization through invariants in n-dimensional Kepler problems
(Pleiades Publishing, 2018) Artículo / Artikulua,
We present a procedure for the normalization of perturbed Keplerian problems in n dimensions based on Moser regularization of the Kepler problem and the invariants associated to the reduction process. The approach allows ...
Orness measurements for lattice m-dimensional interval-valued OWA operators
(Elsevier, 2018) Artículo / Artikulua,
Ordered weighted average (OWA) operators are commonly used to aggregate information in multiple situations, such as decision making problems or image processing tasks. The great variety of weights that can be chosen to ...
Convergent expansions of the confluent hypergeometric functions in terms of elementary functions
(American Mathematical Society, 2018) info:eu-repo/semantics/article,
We consider the confluent hypergeometric function M(a, b; z) for z ∈ C and Rb >Ra > 0, and the confluent hypergeometric function U(a, b; z) for b ∈ C, Ra > 0, and Rz > 0. We derive two convergent expansions of M(a, b; z); ...
