英文摘要Let f be a positive smooth function on a closed Riemann surface (M, g). The f-energy of a map u from M to a Riemannian manifold (N, h) is defined as E(f)(u) = integral(M) f vertical bar del u vertical bar(2)dV(g), and its L(2)-gradient is: tau(f)(u) = f tau(u) + del f . del u. We will study the blow-up properties of some approximate f-harmonic map sequences in this paper. For a sequence u(k) : M -> N with parallel to tau(f)(u(k))parallel to(L2) < C(1) and E(f)(u(k)) < C(2), we will show that, if the sequence is not compact, then it must blow-up at some critical points of f or some concentrate points of vertical bar tau(f)(u(k))vertical bar(2)dV(g). For a minimizing alpha-f-harmonic map sequence in some homotopy class of maps from M into N we show that, if the sequence is not compact, the blow-up points must be the minimal point of f and the energy identity holds true.
