The Kakeya problem for codimension-two planes in $R^{n}$

Chun-Kit Lai, Yixuan Pang, Rahul Sethi +1

We study the $(n - 2)$ -plane Kakeya problem in $R^{n}$ ( $n \geq 4$ ) subject to convex Wolff axioms. In other words, we study finite families of $δ$ -neighborhoods of $(n - 2)$ -plan…

Quantitative Uniqueness and Rough Damping on $T^{2}$

Benjamin Jaye, Rahul Sethi

Motivated by a conjecture of Burq and Gérard, we investigate quantitative uniqueness principles for functions on $T^{2}$ whose Fourier spectra lie in fixed-width annuli. We o…

A High-Frequency Uncertainty Principle for the Fourier-Bessel Transform

Benjamin Jaye, Rahul Sethi

Motivated by problems in control theory concerning decay rates for the damped wave equation $w_{tt} (x, t) + γ (x) w_{t} (x, t) + (- Δ + 1)^{s /2} w (x, t) = 0,$ we consider an analogue of t…

On Simultaneous Triangularization of Matrices and Quasinilpotency of Commutator of Compact Operators

Sasmita Patnaik, Rahul Sethi

In this paper we determine a sufficient condition for the quasinilpotency of a commutator of compact operators via block-tridiagonal matrix form associated with a compact operator.…
