我们证明,在体积趋于无穷的闭双曲三维流形上,存在一列二维扭埃尔米特线丛,其拉普拉斯算子的最小特征值渐近最优。该证明源于离散群强收敛酉表示理论的最新进展。
英文摘要
We prove that there exists a sequence of two-torsion Hermitian line bundles on closed hyperbolic three-manifolds, with volume tending to infinity, and with asymptotically optimal smallest eigenvalue of the Laplacian. The proof stems from recent advances in the program of strongly convergent unitary representations of discrete groups.
