Thanks for the announcement.  A correction on the March 23 talk.  It will be presented jointly by Dr. John Prather and me.  Thanks.

Subject: [Mathregionals] Spring Colloquium Talks

Dear all,

At the suggestion of Todd E. and Vinny, we are planning a spring (and possibly for the coming Fall as well) colloquium series in Athens. The idea is to have more opportunities for math faculty from all groups and all campuses to gather together, share and discuss research and other topics of common interest, and to get to know each other better. If you could give a talk this Spring or this coming Fall, or if you have any suggestions or ideas, please let me or Vinny know.

Dr. Yehong Shao and Dr. Zijian Diao have kindly agreed to give talks (one on Monday, March 2, at 3p.m. and the other on Monday, March 23 at 4:00 pm). The details of their talks are given below. A reminder and the room of the colloquium will be sent out before the talks.

Thank you.

Best,
Wei

Speaker: Dr. Yehong Shao
Date and time: Monday, March 2, at 3p.m.
Location: Athens campus, Morton Hall
Room: TBA.
Title: Hamiltonian Properties in Line Graphs and Iterated Line Graphs
Abstract: attached


Speaker: Dr. Zijian Diao
Date and time: 4:00 pm on March 23.
Location: Athens campus, Morton Hall
Room: TBA.
Title: A tale of three systems (or What MATH 2120 could have been)

Abstract: Non-decimal place value systems, such as binary systems, have been introduced and studied
in many college-level courses in mathematics and computer science, but rarely is this subject front and
center of a math education course.  We propose an unconventional course that immerses students in
non-decimal thinking by focusing on three different number systems: senary, factoradic, and base-infinity.
This course will instill in students a deeper understanding of various concepts in elementary mathematics
such as place values, standard algorithms in arithmetic, divisibility tests, prime factorization, and irrationality.
It can serve as a continuation of the entry-level mathematical education course on basic arithmetic
and number systems, while elevating these topics to a notch below the undergraduate number theory course.
Because of the unusual subject matters under study, this course is also well-suited for nonstandard
pedagogical methods such as discovery-based and inquiry-based learning.
