− V u + Wup = 0 AND ITS PARABOLIC COUNTERPART IN NONCOMPACT MANIFOLDS

We consider the equation ∆u − V (x)u + W (x)u = 0 and its parabolic counterpart in noncompact manifolds. Under some natural conditions on the positive functions V and W , which may only have ‘slow’ or no decay near infinity, we establish existence of positive solutions in both the critical and the subcritical case. This leads to the solutions, in the difficult positive curvature case, of many s...

Uniqueness of Solutions of Ricci Flow on Complete Noncompact Manifolds

We prove the uniqueness of solutions of the Ricci flow on complete noncompact manifolds with bounded curvatures using the De Turck approach. As a consequence we obtain a correct proof of the existence of solution of the Ricci harmonic flow on complete noncompact manifolds with bounded curvatures. Recently there is a lot of study on the Ricci flow on manifolds by R. Hamilton [H1–6], S.Y. Hsu [Hs...

On Complete Noncompact Kähler Manifolds with Positive Bisectional Curvature

We prove that a complete noncompact Kähler manifold Mof positive bisectional curvature satisfying suitable growth conditions is biholomorphic to a pseudoconvex domain of C and we show that the manifold is topologically R2n. In particular, when M is a Kähler surface of positive bisectional curvature satisfying certain natural geometric growth conditions, it is biholomorphic to C2.

Nonlinear Parabolic Problems on Manifolds, and a Nonexistence Result for the Noncompact Yamabe Problem

We study the Cauchy problem for the semilinear parabolic equations ∆u−Ru+ up − ut = 0 on Mn × (0,∞) with initial value u0 ≥ 0, where Mn is a Riemannian manifold including the ones with nonnegative Ricci curvature. In the Euclidean case and when R = 0, it is well known that 1 + 2 n is the critical exponent, i.e., if p > 1+ 2 n and u0 is smaller than a small Gaussian, then the Cauchy problem has ...

Mapping properties of heat kernels, maximal regularity, and semi-linear parabolic equations on noncompact manifolds

Let L : C∞(M ;E)→ C∞(M ;E) be a second order, uniformly elliptic, semipositive-definite differential operator on a complete Riemannian manifold of bounded geometry M , acting between sections of a vector bundle with bounded geometry E over M . We assume that the coefficients of L are uniformly bounded. Using finite speed of propagation for L, we investigate properties of operators of the form f...
