Beltrami operator on digital surfaces which satisfies strong consistency (i.e. pointwise convergence) with respect to the Laplace–Beltrami operator on the underlying manifold when

Related works The Laplace-Beltrami operator being a second order differential operator (divergence of the function gradient, see Sect. 2), a discrete calculus framework is required

Indeed, theoretical analysis on 2D curves shows that one cannot expect convergence of the dicretized Laplacian using exterior calculus toward the real Laplace-Beltrami on Rie-

In all of these cases, the corresponding classical system has a set of initial conditions with non-zero measure for which the orbits are bounded but to which no

Its various discretizations, through graph Laplacians, have inspired many applications in data analysis and machine learning and led to popular tools such as Laplacian EigenMaps
