Noncommutative Harmonic Analysis on Semigroup and Ultracontractivity
We extend some classical results of Cowling and Meda to the noncommutative setting. Let (Tt)t>0 be a symmetric contraction semigroup on a noncommutative space Lp(M), and let the functions φ and ψ be regularly related. We prove that the semigroup (Tt)t>0 is φ-ultracontractive, i.e. ‖Ttx‖∞ ≤ Cφ(t)‖x‖1 for all x ∈ L1(M) and t > 0 if and only if its infinitesimal generator L has the Sobolev embeddi...
متن کاملDynamic Harmonic Modeling and Analysis of VSC-HVDC Systems
Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs a Dynamic Harmonic Domain (DHD) based framework for dynamic harmonic analysis of VSC-HVDC systems. These systems are wide...
متن کاملresponse articles: micro and macro analysis
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
15 صفحه اولMartingales and Harmonic Analysis
A function f : Ω→ R is called F -measurable if f−1(B) := {f ∈ B} := {ω ∈ Ω : f(ω) ∈ B} ∈ F for all Borel sets B ⊆ R. Denote by F 0 the collection of sets in F with finite measure, i.e., F 0 := {E ∈ F : μ(E) <∞}. The measure space (Ω,F , μ) is called σ-finite if there exist sets Ei ∈ F 0 such that ⋃∞ i=0Ei = Ω. If needed, these sets may be chosen to additionally satisfy either (a) Ei ⊆ Ei+1 or (...
