Math 640 (Spring 2021): Suggested EXPERIMENTAL MATHEMATICS Class Projects

https://sites.math.rutgers.edu/~zeilberg/EM21/projs.html

Last Update: May 10, 2021

The Class should be divided into three to six teams, each with a team leader. Each team can contain from 1 to 2 students (including the team leader).

Students should pick a project by April 5, 2021.

The team leader will be in charge of coordinating the various contributions, and writing the first draft of a paper that will be definitely posted here. The first, preliminary, "skeleton" versions should be ready by May 10, 2021, but it is hoped that they will be expanded into publishable papers (at least in arxiv.org, and possibly in a a "real" journal. Each paper should be accopmpanied by at least one Maple package.

See the projects from Spring 2020, See an example from 2019, another example (of a different kind). See also an example from 2018 and another example from 2018.

Statistical Theory of Partitions

Use and extend the procedures done in class for statistical analysis of partitions, satisfying various conditions (odd, distinct, etc.) according to natural "random variables" (number of parts, lagrest part, individually and jointly). Conjecture (and possibly prove) explicit expressions for the expectation, variance, and the scaled moments about the mean and conjecture (or prove) the limiting distributions,

Project Leader: AJ Bu

Other team member: Robert Dougherty-Bliss

Added May 11, 2021: This team wishes to wait for the final version before it is posted. So far they did a great job.

Systematatic Counting of "Latin Triangles" (and Trapezoids), and Designing a game inspired by them

Recently the New Times Magazine started this kind of puzzles,

This projects has two parts

Project Leader (and only member): George Spahn

Added May 10, 2021: Here is the neat app .

[Good job!]

Enjoy!

Investigate the generalized Lehmer conjecture experimentally

One of the famous open problems in number theory is to prove that the Ramanujan τ function, defined by the generating function

Sum(τ(n)*q^n,n=0..infinity) = q*Prod(1-q^i,i=1..infinity)^24

is never zero (Lehmer's conjecture). Investigate natural generalizations from an experimental point of view, and who knows? prove it.

Project Leader: Yuxuan Yang

Other team members: Zidong Zhang

Added May 10, 2021: here is the article and here is the Maple package. [Good job!]

Find experimentally Symmetric Chain Decompositions of Lattices

One way is via "lexicographic greed" due to Aigner in the Boolean lattice case.

Project Leader: Blair Seidler

Other team members: Victoria Chayes

Added May 11, 2021: Here is a a preliminary version. of the project.

Good job, so far.
