Padé continued-fraction coefficient matching conjecture
Padé continued-fraction coefficient matching conjecture
Let be the sequence of numbers generated by Theorem 3, and let be the associated finite continued fractions. Let denote the continued fraction obtained from the Stirling series by the quotient-difference algorithm, with numerator sequence .
Coefficient matching conjecture. In the limit as tends to infinity, the continued fraction agrees with ; equivalently, their numerator sequences satisfy
This conjecture arises from the observed agreement between the coefficients produced by the telescoping method and those of the -fraction for the diagonal Padé approximants to the Stirling series. No proof or disproof is supplied in the excerpt, so the conjecture remains open.
