The Distribution Builder - An innovative tool for decision making: When to sell an asset? with Dr. SixianJin, Department of Mathematics at CSUSM.
An introduction to the innovative and powerful took, “the distribution builder”, for determining the best time to seen an asset. It was originally developed by Nobel laureate Sharpe and his collaborators.
This is a traditional approach to finding the best-selling time that heavily relies on a well-selected “utility function”, which is challenging to describe and needs a lot of math for investors. The core idea of the distribution builder is to encourage investors to express their preferences with a wealth distribution, such as what they aim to achieve at retirement, with much fewer restrictions than choosing a utility function.

Fermat's Last Theorem for n=4 with CSUSM undergraduate student, Dylan Scofield, Department of Mathematics. Faculty advisor is Dr. Hanson Smith.
We will prove that 𝑥⁴ + 𝑦⁴ = 𝑧⁴ has no non-trivial integer solutions. Along the way, we will discuss the history of the famous problem as well as some of the ideas that lead to its eventual full solution.

Title: Stochastic Network Models with Applications to Biology, Computer Science, and Operations Research
Abstract: Stochastic processing networks is a subfield of probability that models situations in which “jobs”, often representing customers, packets of data, or travelers, move through often complex systems in which they receive some sort of “processing”, such as customer support, uploading or downloading, or transportation. I will discuss how tools from this field can be used to model situations such as a store checkout counter, a Wi-Fi network, or a call center. However, the talk will be focused on my application of interest: enzymatic processing. I will show you how tools from probability (specifically stochastic networks) can be used to understand the dynamics of enzymatic processing.

Title: Assessing Differently: An Introduction to Standards-Based GradingAbstract: Have you ever thought about why we grade or if grades we give measure what we want them to? In this presentation, I will introduce the idea of standards-based grading (SBG) and explain how it can be an opportunity to think deeply about these questions while providing students with more equitable grading practices. I will discuss reasons to use this assessment method, introduce some of the big questions one should ask themselves when implementing SBG as well as give examples of implementations from my own classes and from the SBG literature. - Thursday, November 16: Advancement to Candidacy, Iryna Razhkova

Title: Sofya Kovalevskaya and the Cauchy-Kovalevskaya Theorem.
Abstract: Born and raised in Russia in the middle of the 19th century, Sofya
Kovalevskaya had no chance to obtain a higher education in Russia because of her
gender. Overcoming various barriers, she ended up moving to Europe, but faced
new obstacles as a woman in mathematics and science. She wanted to study, be
independent and have a career, which was prohibited in many European countries
in the 19th century. Moreover, she wanted to study mathematics, which considered
a male domain at that time.
Managing all obstacles through her tenacity, self-confidence, and hard work,
she became the first woman in modern Europe to gain a doctorate in mathematics
(at age 24), the first woman appointed to a full professorship in northern Europe
(Stockholm University, Sweden), and the first woman to work for the international
scientific journal (Acta Mathematica) as an editor.
She died young (at age 41), but she wrote nine articles in mathematics and
physics. One of her doctorate dissertations “Zur Theorie der partiallen
Differentialgleichungen” (On the Theory of Partial Differential Equations), which
today is known as Cauchy-Kovalevskaya Theorem, won her valuable recognition
within the European mathematical community. The Cauchy-Kovalevskaya
Theorem gives conditions for the existence of solutions to analytic differential
equations and became a fundamental result in the study of the class of these
equations. - Tuesday, November 21: Graduate Thesis
