Order theory for discrete gradient methods
(Peer reviewed; Journal article, 2022)The discrete gradient methods are integrators designed to preserve invariants of ordinary differential equations. From a formal series expansion of a subclass of these methods, we derive conditions for arbitrarily high ... -
Symbols and exact regularity of symmetric pseudo-splines of any arity
(Journal article; Peer reviewed, 2017)Pseudo-splines form a family of subdivision schemes that provide a natural blend between interpolating schemes and approximating schemes, including the Dubuc–Deslauriers schemes and B-spline schemes. Using a generating ...
