1Centre National de la Recherche Scientifique, Laboratoire Bordelais de Recherche en Informatique, 351 Cours de la Liberation, 33405 Talence Cedex, France.
This study reveals surprising connections between L functions and knot invariants. It uses G. E. Andrews' work to show generating functions for L functions arise from basic hypergeometric functions.
Area of Science:
- Number Theory
- Knot Theory
- Special Functions
Background:
- L functions and their values at nonpositive integers are well-studied.
- Recent findings link these values to coefficients of specialized knot invariants, a surprising connection.
Purpose of the Study:
- To explore the relationship between L functions and knot invariants.
- To provide uniform and general results for generating functions related to L functions.
- To demonstrate these generating functions as specializations of basic hypergeometric functions.
Main Methods:
- Leveraging the foundational work of G. E. Andrews on q-series and hypergeometric series.
- Applying techniques from the theory of special functions.
- Developing general results for generating functions.
Main Results:
- Established a framework to derive generating functions for L functions.
- Demonstrated that these generating functions are specializations of basic hypergeometric functions.
- Obtained generating functions for all nontrivial Dirichlet L functions.
Conclusions:
- The study unifies and generalizes results connecting L functions and knot invariants.
- Highlights the utility of basic hypergeometric functions in understanding L function values.
- Opens new avenues for research at the intersection of number theory and topology.
