“…Here, we will focus on a rather large and popular class of these methods that uses polynomial expansions to model the dependency of the state variables or, directly, the quantity of interest, on the uncertain quantities. Among them, it is worth mentioning methods that propagate highorder Taylor polynomials (Massari et al 2017;Pérez-Palau et al 2015), polynomial chaos expansions (PCE) (Bhusal and Subbarao 2019;Ozen 2017;Gerritsma et al 2010;Schick and Heuveline 2014) and Chebyshev polynomials (Vasile et al 2019).…”
