SPX Calibration of Option Approximations under Rough Heston Model
Mathematics, 2021 The volatility of stock return does not follow the classical Brownian motion, but instead it follows a form that is closely related to fractional Brownian motion.

Padé approximant for refractive index and nonlocal envelope equations [PDF]
, 2009 Padé approximant is superior to Taylor expansion when functions contain poles. This is especially important for response functions in complex frequency domain, where singularities are present and intimately related to resonances and absorption. Therefore

Borel resummation of secular divergences in stochastic inflation
Journal of High Energy Physics, 2023 We make use of Borel resummation to extract the exact time dependence from the divergent series found in the context of stochastic inflation. Correlation functions of self-interacting scalar fields in de Sitter spacetime are known to develop secular IR ...

Padé approximants for inverse trigonometric functions and their applications
Journal of Inequalities and Applications, 2017 The Padé approximation is a useful method for creating new inequalities and improving certain inequalities. In this paper we use the Padé approximant to give the refinements of some remarkable inequalities involving inverse trigonometric functions, it is

, 1961 We present a method in which the Padé approximant is used to calculate the asymptotic behavior of a function from the first few terms of its power series. We illustrate this method by two examples and give a partial justification of it.

New Refinements and Improvements of Some Trigonometric Inequalities Based on Padé Approximant
Journal of Mathematics, 2020 A multiple-point Padé approximant method is presented for approximating and bounding some trigonometric functions in this paper. We give new refinements and improvements of some trigonometric inequalities including Jordan’s inequality, Kober’s inequality,

The RVP Method—From Real Ab-Initio Calculations to Complex Energies and Transition Dipoles
Frontiers in Physics, 2022 The purpose of this review is to describe the rationale behind the RVP (resonance via Padé) approach for calculating energies and widths of resonances, while emphasizing a solid mathematical ground.

Electromagnetic scattering beyond the weak regime: Solving the problem of divergent Born perturbation series by Padé approximants [PDF]
EPJ Web of Conferences, 2020 Electromagnetic scattering is the main phenomenon behind all optical measurement methods where one aims to retrieve the shape or physical properties of an unknown object by measuring how it scatters an incident optical field.
