This innovative book introduces finite and transfinite interpolation methods at a general level in a unifying mathematical style before covering dynamical interpolation methods, which emphasize the underlying Eulerian/Lagrangian dynamics. Transfinite Interpolations and Eulerian/Lagrangian Dynamics: Considers the support of the data set as a geometrically structured set as opposed to an unstructured cloud of points. Is a self-contained graduate-level text, integrating theory, applications, numerical approximations, and computational techniques. Tackles transfinite interpolation methods applied to finite element meshes adaptation and ALE fluid-structure interaction and to the construction of velocity fields from the boundary expression of shape derivatives. Specialists in applied mathematics, physics, mechanics, computational sciences, imaging sciences, and engineering will find this book of interest.
