We study boundedness properties of one-dimensional bilinear singular integral operators with homogeneous kernels whose restriction $\Omega$ to the unit sphere $\mathbb S^1$ has vanishing integral and belongs to $L^q(\mathbb S^1)$ for some $q>1$. Unde

Existence and global regularity results for boundary-value problems of Robin type for harmonic and polyharmonic functions in $n$-dimensional half-spaces are offered. The Robin condition on the normal derivative on the boundary of the half-space is pr

Necessary and sufficient conditions are offered for Sobolev type spaces built on rearrangement-invariant spaces to be continuously embedded into (generalized) Campanato and Morrey spaces on open subsets of the $n$-dimensional Euclidean space. As a co

We prove a sharp criterion for the boundedness of bilinear Fourier multiplier operators associated with symbols obtained by summing all dyadic dilations of a given bounded function $m_0$ compactly supported away from the origin. Our result admits the

Necessary and sufficient conditions are presented for a fractional Orlicz-Sobolev space on $\rn$ to be continuously embedded into a space of uniformly continuous functions. The optimal modulus of continuity is exhibited whenever these conditions are

We prove an $r$-variation estimate, $r>4$, in the norm for ergodic averages with respect to three commuting transformations. It is not known whether such estimates hold for all $r\ge 2$ as in the analogous cases for one or two commuting transformatio

Climate change is expected to affect the frequency and magnitude of floods, which are among the costliest hazards in Europe. As natural hazards have a significant impact on infrastructure and people's lives and their habitats, novel measures to cope

We obtain the optimal open range of $L^{p_1}(\mathbb R^n)\times\cdots\times L^{p_m}(\mathbb R^n)\to L^p(\mathbb R^n)$ bounds for multilinear singular integral operators with homogeneous kernels of the form $\Omega(\frac{y}{|y|})|y|^{-mn}$, where $\Om

The article concerns the issue of arson attacks in Israel.The issue of terrorism in Israel is quite broad, given that it is a very common phenomenon here and Israel deals with terrorism on a daily basis. The paper therefore focuses on incendiary ball
