Our proof makes use of the Hankel determinants built on the Padé approximations to ℓp(x,z).]]> Wed 11 Apr 2018 15:04:15 AEST ]]> Binomial sums related to rational approximations to ζ(4) https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:11929 Wed 11 Apr 2018 10:47:33 AEST ]]> On the complexity of familiar functions and numbers https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:13093 Wed 11 Apr 2018 09:31:47 AEST ]]> A determinantal approach to irrationality https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32649 n/qn with integral pn and qn such that qnξ−pn≠0 for all n and qnξ−pn→0 as n→∞. In this paper, we give an extension of this criterion in the case when the sequence possesses an additional structure; in particular, the requirement qnξ−pn→0 is weakened. Some applications are given, including a new proof of the irrationality of π. Finally, we discuss analytical obstructions to extend the new irrationality criterion further and speculate about some mathematical constants whose irrationality is still to be established.]]> Mon 23 Sep 2019 10:53:04 AEST ]]>
