The 2-weights problem for the Bergman projection and Sarason conjecture.
(2014-09-24)In the early 90's, D. Sarason posed conjectures on the characterization of the boundedness of Toeplitz products on Hardy and Bergman spaces (3). The Hardy space case attracted much attention because of its close relation ... -
The Kolmogorov Law of turbulence: what can rigorously be proved?
(2015-05-15)We define a mathematical framework in which we can specify the Reynolds decomposition and the correlation tensors of an incompressible locally homogeneous and isotropic turbulent flow. After having fixed the technical ... -
The Puerto Rico Tsunami Program after the 2004 Tsunami: Hazard and Vulnerability Assessment, Public Outreach and the Tsunami-Ready Program for Coastal Towns
(2014-06-10)Prior to the 2004 Indian Ocean tsunami the Caribbean island of Puerto Rico had implemented the Puerto Rico Tsunami Warning and Mitigation Program, with a grant from the USA’s FEMA. This program ended in 2003. For several ... -
Tight and Compact Sample Average Approximation for Joint Chance-Constrained Problems with Applications to Optimal Power Flow.
(INFORMS, 2023-08-02)In this paper, we tackle the resolution of chance-constrained problems reformulated via sample average approximation. The resulting data-driven deterministic reformulation takes the form of a large-scale mixed-integer ... -
Towards general purpose LES model of injection and atomization
(2015-05-15)Injection and atomization of liquid is widely used in many industrial and domestic applications such as, fuel injection in engines or burners, spray painting, medical sprays, spray drying, etc. Various approaches are ... -
Towards large scale unfitted adaptive finite element simulations
(2018-04-23)The use of unfitted finite element methods (FEMs) is an appealing approach for different reasons. They are interesting in coupled problems or to avoid the generation of body-fitted meshes. One of the bottlenecks of the ... -
Tsunami-HySEA model validation for tsunami current predictions
(European Geophysical Union, 2016)Model ability to compute and predict tsunami flow velocities is of importance in risk assessment and hazard mitigation. Substantial damage can be produced by high velocity flows, particularly in harbors and bays, even when ... -
Two weight norm inequalities for fractional integrals and commutators
(2014-09-17)In this course we will survey recent work on two weight norm inequalities for the fractional integral operator and its commutator with BMO functions. We are interested in finding sufficient (and necessary and sufficient) ... -
Two-weight norm inequalities for the fractional maximal operator on spaces of homogeneous type
(Institute of Mathematics, Polish Academy of Sciences, 1994) -
Use of Neural Networks for Tsunami Maximum Height and Arrival Time Predictions
(IOAP-MPDI, 2022-06-13)Operational TEWS play a key role in reducing tsunami impact on populated coastal areas around the world in the event of an earthquake-generated tsunami. Traditionally, these systems in the NEAM region have relied on the ... -
Warm-starting constraint generation for mixed-integer optimization: A Machine Learning approach
(Elsevier, 2022-10-11)Mixed Integer Linear Programs (MILP) are well known to be NP-hard (Non-deterministic Polynomial-time hard) problems in general. Even though pure optimization-based methods, such as constraint generation, are guaranteed to ... -
Weighted inequalities for commutators of fractional integrals on spaces of homogeneous type.
(Elsevier, 2006)Let 0 <γ< 1, b be a BMO function and Im γ,b the commutator of order m for the fractional integral. We prove two type of weighted Lp inequalities for Im γ,b in the context of the spaces of homogeneous type. The first one ... -
Weighted weak-type iterated and bilinear Hardy inequalities
(Elsevier, 2023)We characterize the good weights for a certain weighted weak-type iterated Hardy inequality to hold. As a consequence, we get the characterizations of some weighted weak-type bilinear Hardy inequalities.
