A variation on the Pólya-Segő principle in one dimension
Sorina Barza, Martin Lind
We establish a one-dimensional Pólya-Szegő principle for the Riesz -variation , a family of functionals that interpolates between Wiener -variation and t…

Eliminating positive-measure level sets by small Lipschitz perturbations
Sorina Barza, Martin Lind
We establish a new regularity phenomenon of continuous functions. Specifically, given any continuous function and arbitrary , we construct a Lipschitz perturbation w…

Discrete reversed Hardy inequalities and Hölder estimates in Lorentz sequence spaces
Sorina Barza, Anca-Nicoleta Marcoci, Liviu-Gabriel Marcoci
We prove sharp reversed Hardy-type inequalities on the cone of decreasing sequences in weighted -spaces with power weights, applying them to estimate standard norms in Lore…
