Let G be a locally compact unimodular group, and let be some function of n variables on G. To such a , one can associate a multilinear Fourier multiplier, which acts on some n-fold product of the noncommutative -spaces of the group von Neumann algebra…

Given a sequence tending to , we consider the set of Abel universal functions consisting of holomorphic functions f in the open unit disk such that for any compact set K included in the unit circle , different from , the set is dense in the space …

We apply capacities to explore the space–time fractional dissipative equation: (0.1)where and . In this paper, we focus on the regularity and the blow-up set of mild solutions to (0.1). First, we establish the Strichartz-type estimates for the homogen…

We derive three critical exponents for Bernoulli site percolation on the uniform infinite planar triangulation (UIPT). First, we compute explicitly the probability that the root cluster is infinite. As a consequence, we show that the off-critical expon…

We provide an abstract characterization for the Cuntz semigroup of unital commutative AI-algebras, as well as a characterization for abstract Cuntz semigroups of the form for some -space X. In our investigations, we also uncover new properties that th…

We consider two sequences and , , generated by Dirichlet series satisfying a familiar functional equation involving the gamma function . Two general identities are established. The first involves the modified Bessel function , and can be thought of as…

First, we build a computational procedure to reconstruct the convex body from a pre-given surface area measure. Nontrivially, we prove the convergence of this procedure. Then, the sufficient and necessary conditions of a Sobolev binary function to be a…

We use tools from free probability to study the spectra of Hermitian operators on infinite graphs. Special attention is devoted to universal covering trees of finite graphs. For operators on these graphs, we derive a new variational formula for the spe…
