Abstract In conventional Differential Geometry one studies manifolds, locally modelled on R n, manifolds with boundary, locally modelled on [0,∞)× R n− 1, and manifolds with corners, locally modelled on [0,∞) k× R n− k. They form categories Man⊂ M a n b⊂ M a n c. Manifolds with corners X have boundaries∂ X, also manifolds with corners, with dim∂ X= dim X− 1. We introduce a new notion of manifolds with generalized corners, or manifolds with g-corners, extending manifolds with corners, which form a category M a n gc with Man⊂ M a n b⊂ M a n c⊂ M a n gc. Manifolds with g-corners are locally modelled on X P= Hom Mon (P,[0,∞)) for P a weakly toric monoid, where X P≅[0,∞) k× R n− k for P= N k× Z n− k. Most differential geometry of manifolds with corners extends nicely to manifolds with g-corners, including well-behaved boundaries∂ X. In some ways manifolds with g-corners have better properties than manifolds with corners; in particular, transverse fibre products in M a n gc exist under much weaker conditions than in M a n c. This paper was motivated by future applications in symplectic geometry, in which some moduli spaces of J-holomorphic curves can be manifolds or Kuranishi spaces with g-corners rather than ordinary corners. Our manifolds with g-corners are related to the ‘interior binomial varieties’ of Kottke and Melrose [20], and the ‘positive log differentiable spaces’ of Gillam and Molcho [6].
