More Triangular Number Results, Bruce Brandt

Journal of the Minnesota Academy of Science

I define an increasing function from triangular numbers to triangular numbers and prove it preserves [mathematical symbol]. I conjecture that whether a triangular number is in the image of this function is related to the magnitude of [mathematical symbol] on the triangular number. Parallel theorems and conjectures exist for pentagonal numbers. I also make conjectures about the partial sums of [mathematical symbol] on the triangular numbers along with a conjecture about the sums of absolute values of [mathematical symbol] on the squares.

On Translations Of Quadratic Residues, Bruce Brandt

Journal of the Minnesota Academy of Science

The question is posed: Given a set, S, and a positive integer, k, does a function from k to S exist such that, letting x - y if x is a member of a k-tuple going toy, we never have x - y and y - x? The question is linked to whether circular translations of quadratic residues intersect. Several conjectures are made related to the heuristic that quadratic residues are more inclined to intersect their circular translation than other subsets of Z/nZ with the same number of elements.
