• #### Bilinear Calderón--Zygmund theory on product spaces ﻿

(Journal des Math\'ematiques Pures et Appliqu\'ees, 2019-10)
We develop a wide general theory of bilinear bi-parameter singular integrals $T$. This includes general Calder\'on--Zygmund type principles in the bilinear bi-parameter setting: easier bounds, like estimates in the Banach ...
• #### Quantitative weighted estimates for Rubio de Francia's Littlewood--Paley square function ﻿

(Journal of Geometric Analysis, 2019-12)
We consider the Rubio de Francia's Littlewood--Paley square function associated with an arbitrary family of intervals in $\mathbb{R}$ with finite overlapping. Quantitative weighted estimates are obtained for this operator. ...
• #### An optimal scaling to computationally tractable dimensionless models: Study of latex particles morphology formation ﻿

(Computer Physics Communications, 2020-02)
In modelling of chemical, physical or biological systems it may occur that the coefficients, multiplying various terms in the equation of interest, differ greatly in magnitude, if a particular system of units is used. Such ...
• #### Some geometric properties of Riemann’s non-differentiable function ﻿

(Comptes Rendus Mathematique, 2019-11-06)
Riemann’s non-differentiable function is a celebrated example of a continuous but almost nowhere differentiable function. There is strong numeric evidence that one of its complex versions represents a geometric trajectory ...
• #### Computing Multipersistence by Means of Spectral Systems ﻿

(Proceedings of the 2019 on International Symposium on Symbolic and Algebraic Computation, 2019-07-08)
In their original setting, both spectral sequences and persistent homology are algebraic topology tools defined from filtrations of objects (e.g. topological spaces or simplicial complexes) indexed over the set Z of integer ...
