SEMINAR IN FUNCTIONAL ANALYSIS
AND RELATED AREAS
Wednesday, February 19, 2025
5:15 p.m. - 6:15 p.m. (including a coffee break)
SPEAKER: Michael Somos
The Catholic University of America
TITLE: Spherical Triangles in the Elliptic Realm
ABSTRACT: Spherical triangles have a very ancient history. Also, planar triangles with rational sides and area using Heron's formula for the area. Despite some continuing interest in Heronian spherical triangles, I do not know of any published examples of non-trivial numerical spherical triangles with Heronian sides, angles and area. Here a "Heronian angle" refers to an angle where the tangent of its half is rational. After some research I was able to find infinite families of Heronian spherical triangles. This is closely related to my research in the Elliptic Realm which includes elliptic functions and curves. I will talk about early 19th century work relating the spherical law of sines to Jacobi elliptic functions. I will mention how this relates to functional equations associated with some identities in my Simple Algebraic Identities collection.
PLACE: Aquinas Hall, room 108.
ORGANIZERS: V. Bogdan (The Catholic University of America), P. Kainen (Georgetown University), R. Kalpathy (The Catholic University of America), and A. Levin (The Catholic University of America).
