Corrected Fourier series and its application to function approximation.
Correction to the paper "On convergence of Fourier series of functions of generalized bounded variation" (Studia Math., 44 (1972), pp. 107-117)
Corrections to the Papers "Power Bounded Matrices of Fourier-Stieltjes Transforms I, II".
Corrigenda to: "Generalizations of theorems of Fejér and Zygmund on convergence and boundedness of conjugate series" (Studia Math. 57 (1976), 241-249)
Proposition 4.1(i) of [1] is incorrect, i.e. the sequence of Cesàro-sections of a sequence x in a translation invariant BK-space is not necessarily bounded. Theorem 4.2(ii) of [1] and the proof of Proposition 4.3 of [1] are corrected. All other statements of [1], including Proposition 4.3 itself, are correct.
Corrigendum: On summability of Fourier series.
Counterexamples for classical operators on Lorentz-Zygmund spaces
Coup d'oeil sur la théorie des séries trigonométriques les plus usuelles, et sur une raison naturelle de leur convergence, applicable aux autres développements de fonctions arbitraires employés en Physique mathématique
Criteria for absolute and strong convergence of Fourier series
Critical length for a Beurling type theorem
In a recent paper [3] C. Baiocchi, V. Komornik and P. Loreti obtained a generalisation of Parseval's identity by means of divided differences. We give here a proof of the optimality of that theorem.
