Expository talks, notes, seminars,
conferences, etc. in reversed chronological order.
01/17/2020 [conference], Joint Math Meetings 2020
Special session
"Geometry of Differential Equations", Denver, Colorado
Fall 2019 [seminar],
${\rm G_2}$ Seminar, CU Boulder
A reading seminar on the algebraic aspects of the
exceptional Lie group $G_2$ for PhD students at CU Boulder.
09/18/2019 [talk], Shapes of Constant Width and Beyond
This is a colloquium delivered at the Math Club of CU Boulder. Some of the material
is based on an undergraduate summer research project (DoMath) at Duke University in
the summer of 2018. The project was co-supervised by Prof. Robert Bryant and myself.
The group members were Sandra Martha Batakana, Zephyr Farah and Qinzhe Liu.
11/02/2016 [talk], Calculus of Variations via Exterior Differential Systems
This is the note for a talk given at the student-organized GTGS seminar at Duke.
The main purpose of this talk is to introduce an EDS approach to 1-dimensional variational problems.
10/21/2016 [talk], Darboux Integrability of Hyperbolic Systems and Lie's Theorem
This is the note for a talk given at the Exterior Differential Systems/Method of Equivalence Seminar at Duke.
Lie's theorem on the Darboux integrability of f-Gordon equations is presented.
