Towards A Baker-Campbell-Hausdorff Theorem In Positive Characteristic, Nikolas A. Koutroulakis

College of Graduate Studies: Theses & Dissertations

We investigate whether there is an analog of the Baker-Campbell-Hausdorff (BCH) theorem for Lie algebras over fields of positive characteristic. We begin by introducing the proof of the BCH formula in characteristic zero. We then introduce the Artin-Hasse exponential and show that it is $p$-integral. Our main result provides sufficient conditions under which a BCH-type formula exists for the Artin-Hasse exponential in positive characteristic. Additionally, we derive a formula for computing an inverse of the Artin-Hasse exponential.

Quantifying Inositol Phosphate Dephosphorylation To Understand The Role Of Recalcitrant Organic Phosphorus Forms On Harmful Algal Blooms In Freshwater Systems, Iffat Tasnim

College of Graduate Studies: Theses & Dissertations

Organophosphorus such as phytic acid, a surrogate species of inositol phosphate (IP), may serve as a source for orthophosphate (OP) in freshwater. In absence of OP, competent aquatic microorganisms upregulate the production of specialized enzymes to obtain growth-sustaining OP from organic phosphorus (org-P) forms. The contribution of recalcitrant org-P to the OP pool has been overlooked due to the lack of capable tools to measure OP production from org-P accurately. The objective of this study was to quantify OP production from phytic acid (a surrogate form of recalcitrant org-P) to assess the contribution of recalcitrant org-P forms to the total …

I compared a large data set of ichthyoplankton surveys completed from 2009-2011 to a replicated six-month sampling period from May – November of 2024. Collection was conducted weekly to biweekly during night flood tides using a fixed suspension ichthyoplankton net (1mm …

Community And Decomposition Dynamics Along A Saltwater Intrusion Gradient On Sapelo Island, Georgia, Zach Gordon

College of Graduate Studies: Theses & Dissertations

Saltwater intrusion, the movement of ocean water into freshwater, is a significant global threat to coastal freshwater ecosystems linked to both climate change and anthropogenic influences. Alterations to coastal landscapes can increase intrusion. Sapelo Island has an extensive history of agricultural landscape alteration, but freshwater flow decline increased the movement of saltwater inland by tides. Intrusion is expected to increase in frequency and magnitude due to rising sea levels and storms. Salinization puts inland habitats and the humans relying on them at risk. As saltwater is denser than freshwater, more pressure is placed on benthic organisms (i.e., macroinvertebrates) that will …
