论文摘要
我们计算Laplace-Beltrami操作员的光谱,1形式的Laplacian和Einstein操作员在正弦角上的对称性2张仪上的Einstein oberator上,在Einstein阳性歧管(M,G)$上。我们得出结论,在$(m,g)$的哪些条件下,正弦孔在奇异的ricci-de turck流动下动态稳定,刚性作为单数爱因斯坦歧管
We compute the spectra of the Laplace-Beltrami operator, the connection Laplacian on 1-forms and the Einstein operator on symmetric 2-tensors on the sine-cone over a positive Einstein manifold $(M, g)$. We conclude under which conditions on $(M,g)$, the sine-cone is dynamically stable under the singular Ricci-de Turck flow and rigid as a singular Einstein manifold
