-extrapolation via non-local decay estimates: theory and applications to the generalized Stokes operator with rough coefficients
Luca Haardt
In this article, we establish -mapping properties for the generalized Stokes operator with bounded measurable coefficients on the full range of exponents that is know…
A coherent theory of tent spaces and homogeneous Triebel-Lizorkin spaces
Luca Haardt
We introduce and systematically investigate a scale of tent spaces that characterizes homogeneous Triebel-Lizorkin spaces . These spaces generalize the cla…
A new scale of function spaces characterizing homogeneous Besov spaces
Pascal Auscher, Sebastian Bechtel, Luca Haardt
We introduce and study a new scale of function spaces that characterize the homogeneous Besov spaces , hence completing earlier work by Ullrich. These new…
On Kato's Square Root Property for the Generalized Stokes Operator
Luca Haardt, Patrick Tolksdorf
We establish the Kato square root property for the generalized Stokes operator on with bounded measurable coefficients. More precisely, we identify the domain of the…
Physical interpretation of the UV/X-ray variability behavior of NGC 7469
P. O. Petrucci, L. Maraschi, F. Haardt +1
We present a re-analysis of the simultaneous 30 day IUE/XTE observation of NGC 7469 done in 1996. Our main progress, in comparison to previous spectral analysis, is to adopt and fi…
