The Reverse Mathematics of wqos and bqos [PDF]
In this paper we survey wqo and bqo theory from the reverse mathematics perspective. We consider both elementary results (such as the equivalence of different definitions of the concepts, and basic closure properties) and more advanced theorems.

The effectiveness of filliped learning method on attitude and academic performance in Mathematics in elementary schools [PDF]
Background and Objectives: One of the problems of elementary school teachers is the lack of time, especially in mathematics. Lack of time to educate students has caused academic failure and weakened the basic math of elementary students. For this reason,

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 ...

ERNA and Friedman's Reverse Mathematics [PDF]
AbstractElementary Recursive Nonstandard Analysis, in short ERNA, is a constructive system of nonstandard analysis with a PRA consistency proof, proposed around 1995 by Patrick Suppes and Richard Sommer. Recently, the author showed the consistency of ERNA with several transfer principles and proved results of nonstandard analysis in the resulting ...

Devito (v3.1.0): an embedded domain-specific language for finite differences and geophysical exploration [PDF]
We introduce Devito, a new domain-specific language for implementing high-performance finite-difference partial differential equation solvers. The motivating application is exploration seismology for which methods such as full-waveform inversion and ...
