Espectro do laplaciano ponderado e hipersuperfícies em gradient Ricci solitons
We obtain upper estimates to the greatest lower bound of the essential spectrum of weighted Laplacian operator of non-compact weighted manifold under assumptions of the weighted volume growth. Furthermore, we find examples where the equality occurs in the es- timates obtained. As a consequence, we gi...
