Partial impredicativity in reverse mathematics [PDF]
AbstractIn reverse mathematics, it is possible to have a curious situation where we know that an implication does not reverse, but appear to have no information on how to weaken the assumption while preserving the conclusion (other than reducing all the way to the tautology of assuming the conclusion).

Reverse mathematics and colorings of hypergraphs [PDF]
Working in subsystems of second order arithmetic, we formulate several representations for hypergraphs. We then prove the equivalence of various vertex coloring theorems to ${\sf WKL}_0$, ${\sf ACA}_0$ and $Π^1_ 1$-${\sf CA}_0$.

Reverse-engineering Reverse Mathematics
Abstract An important open problem in Reverse Mathematics (Montalban, 2011 [16] ; Simpson, 2009 [25] ) is the reduction of the first-order strength of the base theory from I Σ 1 to I Δ 0 + exp . The system ERNA, a version of Nonstandard Analysis based on the system I Δ 0 + exp , provides a partial ...
