BochnerRiesz Means at the Critical Index: Weighted and Sparse Bounds
[OWP202316] (Mathematisches Forschungsinstitut Oberwolfach, 20231127)We consider BochnerRiesz means on weighted $L^p$ spaces, at the critical index $\lambda(p)=d(\frac 1p\frac 12)\frac 12$. For every $A_1$weight we obtain an extension of Vargas' weak type $(1,1)$ inequality in some range ...

[OWR202325] (2023)  (04 Jun  09 Jun 2023)The workshop "Incidence Problems in Harmonic Analysis, Geometric Measure Theory, and Ergodic Theory" covered interactions between geometric problems involving fractals, dimensions, patterns, projections and incidences, and ... 
1751  Mathematical Instruments between Material Artifacts and Ideal Machines: Their Scientific and Social Role before 1950
[OWR201758] (2017)  (17 Dec  23 Dec 2017)Since 1950, mathematicians have become increasingly familiar with the digital computer in their professional practice. Previously, however, many other instruments, now mostly forgotten, were commonly used to compute numerical ... 
MehlerHeine asymptotics of a class of generalized hypergeometric polynomials :
[OWP201323] (Mathematisches Forschungsinstitut Oberwolfach, 20131029)We obtain a Mehler–Heine type formula for a class of generalized hypergeometric polynomials. This type of formula describes the asymptotics of polynomials scale conveniently. As a consequence of this formula, we obtain ...

A Note on Endpoint BochnerRiesz Estimates
[OWP202317] (Mathematisches Forschungsinstitut Oberwolfach, 20231127)We revisit an $\varepsilon$removal argument of Tao to obtain sharp $L^p \to L^r(L^p)$ estimates for sums of BochnerRiesz bumps which are conditional on nonendpoint bounds for single scale bumps. These can be used to ... 
On Weak Weighted Estimates of Martingale Transform
[OWP201622] (Mathematisches Forschungsinstitut Oberwolfach, 20161112)We consider several weak type estimates for singular operators using the Bellman function approach. We disprove the $A_1$ conjecture, which stayed open after MuckenhouptWheeden's conjecture was disproved by RegueraThiele.
