该研究构造了一对非全等、严格凸且边界为实解析的平面区域,其Steklov谱(含重数)相同,否定了平面Steklov型的Kac问题,且该区域可在$C^\text{\infty}$拓扑下任意接近圆盘。

我们构造了一对非全等的有界欧氏平面区域,它们具有相同的Steklov谱(含重数),这对平面Steklov型的Kac问题“能否‘听出’鼓的形状?”给出了否定答案。这些区域是单连通、严格凸的,具有实解析边界,且在$C^\text{\infty}$拓扑下可任意接近圆盘。
英文摘要
We construct pairs of noncongruent bounded Euclidean plane domains with identical Steklov spectra, including multiplicities. This gives a negative answer to the planar Steklov analogue of Kac's question ``Can one hear the shape of a drum?'' The domains are simply connected and strictly convex, have real-analytic boundaries, and may be chosen arbitrarily close to a disk in the $C^\infty$ topology.
