英文摘要 | We study the positive solutions to a class of general semilinear elliptic equations Delta u(x) + uh(ln u) = 0 defined on a complete Riemannian manifold (M, g) with Ric(g) >= -K g, and obtain Li-Yau-type gradient estimates of positive solutions to these equations which do not depend on the bounds of the solutions or the Laplacian of the distance function on (M, g). We also obtain some Liouville-type theorems for these equations when (M, g) is non-compact and Ric(g) >= 0 and establish some Harnack inequalities as consequences. As applications of the main theorem, we extend our techniques to the Lichnerowicz-type equations Delta u+lambda(1)u+lambda(2)u ln u+lambda(3)u(b+1)+lambda(4)u(p+1) = 0, the Einstein-scalar field Lichnerowicz equations Delta u+lambda(1)u+lambda(2)u(b+1)+lambda(3)u(p+1) = 0 with dim M >= 3 and the two-dimensional Einstein-scalar field Lichnerowicz equation Delta u + Ae(2u) + Be-2u + D = 0, and obtain some similar gradient estimates and Liouville theorems under some suitable analysis conditions on these equations. |
