On the Structure of μ-Classes
We prove that, if μ < ⌊n/2⌋, then every rational parametrization of degree n and class μ is a limit of parametrizations of the same degree and class μ + 1. This property was conjectured in Cox, D., Sederberg, T., Chen, F. [Cox, D., Sederberg, T., Chen, F. (1998b)] and its validity allows an expli...

| Sumario: | We prove that, if μ < ⌊n/2⌋, then every rational parametrization of degree n and class μ is a limit of parametrizations of the same degree and class μ + 1. This property was conjectured in Cox, D., Sederberg, T., Chen, F. [Cox, D., Sederberg, T., Chen, F. (1998b)] and its validity allows an explicit description of the variety of parametrizations of degree n and class μ, for all (n, μ). |
