| Περίληψη: | In this paper, we extend the symplectic quandle method, previously employed in our study of parabolic representations of knot groups, to investigate the general S L (2 , ℂ) -representations of 2-bridge "kmot" groups. We introduce a 'generalized symplectic quandle structure' corresponding to ( M , conjugation) for each M ∈ ℂ \ { 0 , 1 , − 1 } , where M = { A ∈ S L (2 , ℂ) | t r (A) = M + M − 1 }. By converting the system of conjugation quandle equations to that of generalized symplectic quandle equations, we obtain a simpler expression for the 2-variable Riley polynomial and derive some recursive formulas for Riley polynomials and Alexander polynomials. This approach enables us to effectively compute the A-polynomials, allowing us to obtain numerous previously unknown A-polynomials within minutes using Mathematica. [ABSTRACT FROM AUTHOR] |
