A Mathematical Problem-Solving Pipeline (MPSP) to strengthen scaffolding in higher education STEM courses
Rochelle E. Tractenberg, Andrew C. Lee, Rachelle DeCoste
We outline a new tool that can promote coherence within and across higher education mathematics courses by focusing on problem-solving: the Mathematical Problem-Solving Pipeline or…
Abelian Factor in 2-step Nilpotent Lie Algebras Constructed from Graphs
Rachelle DeCoste, Lisa DeMeyer, Meera Mainkar +1
We consider real 2-step metric nilpotent Lie algebras associated to graphs with possibly repeated edge labels as constructed by Ray in 2016. We determine how the structure of the e…
Graphs and Metric 2-step Nilpotent Lie Algebras
Rachelle DeCoste, Lisa DeMeyer, Meera Mainkar
Dani and Mainkar introduced a method for constructing a 2-step nilpotent Lie algebra from a simple directed graph in 2005. There is a natural inner product on…
The multiplicity of weights in nonprimitive pairs of weights
Rachelle C. DeCoste
For each type of classical Lie algebra, we list the dominant highest weights for which is not a primitive pair and the weight space has dimension one where…
Center Manifold and Lie Symmetry Calculations on a Quasi-chemical Model for Growth-death Kinetics in Food
Rachelle DeCoste, Louis Piscitelle
Food scientists at the U.S. Army's Natick Solider Center have developed a model for the lifecyle of the bacteria Staphylococcus aureus in intermediate moisture bread. In this artic…
Closed Geodesics on Compact Nilmanifolds with Chevalley Rational Structure
Rachelle DeCoste
We continue the study of the distribution of closed geodesics on nilmanifolds constructed from a simply connected 2-step nilpotent Lie group with a left invariant metric and a latt…
