Fast and accurate con-eigenvalue algorithm for optimal rational approximations
Fast accurate con-eigenvalue algorithm optimal rational approximations
2011/2/21
The need to compute small con-eigenvalues and the associated con-eigenvectors of
positive-definite Cauchy matrices naturally arises when constructing rational approximations with an optimally small L...
Lyapunov spectrum for exceptional rational maps
Lyapunov spectrum exceptional rational maps
