Duality in a stability problem for some functionals arising in interpolation theory
Anton Tselishchev
By using duality, it is shown that there exist near-minimizers for the distance functionals for the couple , , that are stable under the action of sing…

Stability of nearly optimal decompositions in Fourier Analysis
Anton Tselishchev
The question of existence is treated for near-minimizers for the distance functional (or -functional in the interpolation terminology) that are stable under the action of certai…
