Positive Definiteness of Functions with Applications to Operator Norm Inequalities
ISBN: 9780821853078 / Angielski / Miękka / 2011 / 80 str. Termin realizacji zamówienia: ok. 30 dni roboczych (Bez gwarancji dostawy przed świętami) Positive definiteness is determined for a wide class of functions relevant in the study of operator means and their norm comparisons. Then, this information is used to obtain an abundance of new sharp (unitarily) norm inequalities comparing various operator means and sometimes other related operators.

Means of Hilbert Space Operators
ISBN: 9783540406808 / Angielski / Miękka / 2003 / 156 str. Termin realizacji zamówienia: ok. 22 dni roboczych (Bez gwarancji dostawy przed świętami) The monograph is devoted to a systematic study of means of Hilbert space operators by a unified method based on the theory of double integral transformations and Peller's characterization of Schur multipliers. General properties on means of operators such as comparison results, norm estimates and convergence criteria are established. After some general theory, special investigations are focused on three one-parameter families of A-L-G (arithmetic-logarithmic-geometric) interpolation means, Heinz-type means and binomial means. In particular, norm continuity in the parameter is examined for...
