Abstract: In 2008, Kaneko made several interesting observations about the values of the modular j invariant at real quadratic irrationalities. The values of modular functions at real quadratics are defined in terms of their cycle integrals…

Abstract: We establish a precise Schwarz lemma for real-valued and bounded harmonic functions in the real unit ball of dimension n. This extends Chen’s Schwarz-Pick lemma for real-valued and bounded planar harmonic mapping.

Abstract: Abstract The main goal of this work is classifying the singularities of slice regular functions over a real alternative ⁎-algebra A. This function theory has been introduced in 2011 as a higher-dimensional generalization of the…

Abstract: A characterization is obtained for the Fourier transform of functions belonging to ℒ2(ℝ,H), where H denotes a Hilbert C∗-module. But in the case of functions belonging to L1(ℝ,H) a similar result is proved when H…
