Mathematics and Statistics Colloquium for 2017


Title of Talk



Dr. Dennis Bell / UNF

Associative Binary Operations and the Pythagorean Theorem

 Abstract: The Pythagorean Theorem is one of the oldest and most famous results in geometry, perhaps in all of mathematics. The theorem is known to every school- boy and girl. It has been given hundreds of different proofs over the ages. About 20 new proofs were discovered by Dr. Tong and his students alone! In this talk we present a new angle on the Pythagorean theorem (no pun intended). The idea is to derive the well-known formula from certain “obvious” qualitative properties. This novel approach to PT was initiated by L. Berrone in a paper in the American Mathematical Monthly and continued by the speaker. It has the interesting feature of bringing together two very different branches of mathematics, the ancient subject of Euclidean geometry and the much more recent area of functional equations. Along the way, a surprising proof pops out.

Information regarding the Quantun Theory and Matrix Analysis

Here are some sources on quantum information theory.

1- Nielsen's book:

 This is one of the most famous and most cited books in the history (~30200 citations)


2- Majorization in quantum information theory (again this is a paper of Nielsen):


3- Another book is

Freakin's Big Numbers 

Abstract: We all know that numbers go on forever; numbers are infinite.  But what numbers do we actually use?  What are the biggest numbers that show up in science and mathematics?  In this talk, we present some of these really big numbers that show up in physics, number theory, cryptography, and graph theory.  Then we laugh at their puny existence as we learn about Graham’s Number, a Guinness Book of World Record holder for the biggest number ever used in a mathematics proof.

Mr. Chudamani Poudyal  T-Estimation of Claim Severity Distributions Abstract: Parametric statistical models for insurance claims severity are continuous, right-skewed, and frequently heavy-tailed. The data sets that such models are usually fitted to contain outliers that are difficult to identify and separate from genuine data. Moreover, due to commonly used actuarial \loss control schemes", the random variables we observe and wish to model are an ected by truncation (due to deductibles), censoring (due to policy limits), scaling (due to coinsurance proportions) and other transformations. In the current practice, statistical inference for loss models is almost exclusively likelihood based, which typically results in non-robust parametric estimators, pricing models, and risk measures. In this talk, we redesign the method of trimmed moments (Brazauskas, Jones, Zitikis, 2009) to accommodate the loss variable transformations, establish its asymptotic and small-sample properties, and study its practical performance in applications. For numerical illustrations, we use the Norwegian Fire Claims Data Set for the year 1975. Tuesday, Feb. 20th

Dr. Jae-Ho Lee Leonard pairs Abstract: Roughly speaking, a Leonard pair consists of two diagonal linear transformations on a finite-dimensional vector space, each of which acts in an irreducible tridiagonal fashion on an eigenbasis for the other one. In this talk, we give several examples of Leonard pairs and illustrate how Leonard pairs arise in representation theory and the theory of orthogonal polynomials. This talk is aimed at an undergraduate audience with little background in linear algebra. We do not assume prior knowledge of representation theory or the theory of orthogonal polynomials.

Mr. Joseph Ferrara
Product Manager, GleanView
The link between college and workplace Former UNF student and UNF SIAM officer Joseph Ferrara will join us to talk about the link between college and workplace as a Math/Stat major. He will talk about his experiences and also what employers need from math/stat majors. Before his talk we will also have an open discussion about SIAM in general and what our club has to offer.
