Second order arithmetic

WebSecond-order exact numerical estimates in time and space are obtained. The unconditional stability and convergence of the method are tested. Two numerical examples are also presented and compared with the exact solution.

WebAbstract. This paper addresses the structures (M, ω) and (ω, SSy (M)), where M is a nonstandard model of PA and ω is the standard cut. It is known that (ω, SSy (M)) is interpretable in (M, ω). Our main technical result is that there is an reverse interpretation of (M, ω) in (ω, SSy (M)) which is ‘local’ in the sense of Visser [11].
