| 520 | 3 | |a It is well-known that numerically approximating calculus of variations problems possessing a Lavrentiev Gap Phenomenon (LGP) is challenging, and the standard numerical methodologies such as finite element, finite difference, and discontinuous Galerkin methods fail to give convergent methods because they cannot overcome the gap. This paper is a continuation of a 2018 paper by Feng-Schnake, where a promising enhanced finite element method was proposed to overcome the LGP in the classical Manià's problem. The goal of this paper is to provide a complete \(\Gamma\)-convergence proof for this enhanced finite element method, hence establishing a theoretical foundation for the method. The crux of the convergence analysis is the construction of a new finite element interpolant that helps to build a recovery sequence for proving a \(\Gamma\)-convergence result due to its strong approximation properties in Sobolev spaces. Numerical tests are also provided to verify the theoretical results. | |
