Francisco M. Bersetche, Juan Pablo Borthagaray

摘要:

在本文中,我们考虑积分分数拉普拉斯算子的Neumann问题的连续,分段线性有限元的近似。我们分析了这类问题的弱形式,包括它们的适定性和解的渐近行为。我们解决的有限元离散的收敛性和讨论的方法的实施。最后,我们提出了几个数值实验中的一维和二维域,说明该方法的性能以及某些属性的解决方案。

英文摘要:

In this paper we consider approximations of Neumann problems for the integral fractional Laplacian by continuous, piecewise linear finite elements. We analyze the weak formulation of such problems, including their well-posedness and asymptotic behavior of solutions. We address the convergence of the finite element discretizations and discuss the implementation of the method. Finally, we present several numerical experiments in one- and two-dimensional domains that illustrate the method's performance as well as certain properties of solutions.
