Ramsey Orderly Algebras as a New Approach to Ramsey Algebras
Wen Chean Teh, Zu Yao Teoh
Ramsey algebras are algebras that induce Ramsey spaces, which are generalizations of the Ellentuck space and Milliken's space. Previous work suggests a possible local version of Ra…
Parikh matrices and Parikh Rewriting Systems
Wen Chean Teh
Since the introduction of the Parikh matrix mapping, its injectivity problem is on top of the list of open problems in this topic. In 2010 Salomaa provided a solution for the terna…
Ramsey Algebra and the Existence of Idempotent Ultrafilters
Wen Chean Teh
Hindman's Theorem says that every finite coloring of the positive natural numbers has a monochromatic set of finite sums. Ramsey algebras, recently introduced, are structures that…
Parikh Matrices and Strong M-Equivalence
Wen Chean Teh
Parikh matrices have been a powerful tool in arithmetizing words by numerical quantities. However, the dependence on the ordering of the alphabet is inherited by Parikh matrices. S…
