Abstract:
We discuss the existence and stability of Riesz bases of exponential type of $L^2(T)$ for special domains $T\subset \mathbb {R}^2$ called trapezoids, and we construct exponential bases on the finite union of rectangles with the same height. We also generalize our main theorems in dimension $d\ge 3$.References
