AboutAbout the lab
Exploring convex polytopes through geometry and combinatorics
The Discrete Geometry Lab studies the properties of convex polytopes from both geometric and combinatorial perspectives.
Commutative rings associated with convex polytopes are also a subject of study.
Through this research and education, the lab also aims at applications in information science.
The lab's faculty describe their research topic as algebraic combinatorics.
Key terms
- Convex polytope
- A solid bounded by flat faces in which the line segment joining any two points inside never leaves the solid. A cube is an example.
- Combinatorics
- A field of mathematics that studies the rules for counting, arranging, and combining objects.
- Commutative ring
- A set in which you can add, subtract, and multiply, and where changing the order of multiplication does not change the result. The integers are an example.
ResearchResearch themes
