Infrastructures and Global Fields.

The following posts give an introduction to infrastructures and how to obtain these from global fields:

  1. The Discrete Logarithm Problem and Generalizations.
  2. One-dimensional Infrastructures.
  3. Interpreting One-dimensional Infrastructures as Groups: f-Representations.
  4. n-dimensional Infrastructures.
  5. How to Obtain Reduction Maps for n-dimensional Infrastructures.
  6. Obtaining Infrastructures from Global Fields.
