A new type of Taylor series expansion [PDF]

open access: yesJournal of Inequalities and Applications, 2018
We present a variant of the classical integration by parts to introduce a new type of Taylor series expansion and to present some closed forms for integrals involving Jacobi and Laguerre polynomials, which cannot be directly obtained by usual symbolic ...

Newton series expansion of bosonic operator functions

open access: yesSciPost Physics, 2021
We show how series expansions of functions of bosonic number operators are naturally derived from finite-difference calculus. The scheme employs Newton series rather than Taylor series known from differential calculus, and also works in cases where the ...

Properties of Poincaré half-maps for planar linear systems and some direct applications to periodic orbits of piecewise systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
This paper deals with fundamental properties of Poincaré half-maps defined on a straight line for planar linear systems. Concretely, we focus on the analyticity of the Poincaré half-maps, their series expansions (Taylor and Newton–Puiseux) at the ...
