The Toroidal Embedding Arising From an Irrational Fan
The Toroidal Embedding Arising From an Irrational Fan
A toroidal embedding is defined which does not assume the fan consists of rational cones. For a rational fan, the toroidal embedding is the usual toric variety. If the fan is not rational, the toroidal embedding is in general a quasi-compact noetherian locally ringed space which is not a scheme. …
