Lebesgue-type inequalities in greedy approximation

30 Sep 2019 Dilworth Stephen Garrigos Gustavo Hernandez Eugenio Kutzarova Denka Temlyakov Vladimir

We present new results regarding Lebesgue-type inequalities for the Weak Chebyshev Greedy Algorithm (WCGA) in uniformly smooth Banach spaces. We improve earlier bounds in Temlyakov (Forum Math Sigma 2014), for dictionaries satisfying a new property introduced here... (read more)
