An Optimal Unramified Tower of Function Fields

    Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


    Efficient construction of long algebraic geometric--codes resulting from optimal towers of function fields is known to be difficult. In the following a tower which is both optimal and unramified after its third level, is investigated in the hope that its simple ramification structure can be exploited in the construction of algebraic geometric--codes. Results are mostly negative, but help clarifying the difficulties in computing bases of Riemann--Roch spaces.
