Inf-convolution and regularization of convex functions on Riemannian manifolds of nonpositive curvature.

Daniel Azagra, Juan Ferrera (2006)

Revista Matemática Complutense

Similarity:

We show how an operation of inf-convolution can be used to approximate convex functions with C smooth convex functions on Riemannian manifolds with nonpositive curvature (in a manner that not only is explicit but also preserves some other properties of the original functions, such as ordering, symmetries, infima and sets of minimizers), and we give some applications.

On the L-pointwise regularity of functions in critical Besov spaces.

Similarity:

We show that the functions in L(R) given by the sum of infinitely sparse wavelet expansions are regular, i.e. belong to C  (x), for all x ∈ R which is outside of a set of vanishing Hausdorff dimension.
