摘要：Using canonical representatives in hyperbolic groups and the decidability of the Diophantine theory of free semigroups with paired alphabet, we solve the isomorphism problem for hyperbolic groups with no (essential) small action on a real tree. The solution enables computation of the outer automorphism group of such groups and implies the homeomorphism problem for ''weakly geometric'' 3-manifolds, closed hyperbolic manifolds, and negatively curved ones of dimension greater than or equal to 5. ...

摘要：We obtain a complete description of the Lie algebra of complete holomorphic vector fields on the universal cover of a compact complex manifold with negative first Chern class. The main tools are an equivariance result we prove for harmonic maps and the rigidity theory for harmonic maps from Kahler manifolds to locally symmetric spaces.
