Pointwise character bounds for $SU (3)$

Yunfeng Zhang

We present a basic pointwise bound for the irreducible characters of $SU (3)$ and, as an application, derive new $L^{p}$ bounds for these characters. Our approach is based on…

Growth of Fourier--Lebesgue norms for mKdV

Saikatul Haque, Rowan Killip, Monica Visan +1

We demonstrate inflation of Fourier--Lebesgue norms for solutions to the focusing modified Korteweg--de Vries equation posed on the real line. For $p \neq = 2$ and all $s\in \mathbb{R…

Algebraic and analytic properties of invariant differential operators on a homogeneous space of complexity $1$

Hanlong Fang, Xiaocheng Li, Yunfeng Zhang

Denote by $S L_{3} (R)$ the special linear group of degree 3 over the real numbers, $A$ the subgroup consisting of the diagonal matrices with positive entries. In this paper, w…
