    At the regular monthly noon meeting of the Dallas Petroleum Geologists on Monday, May 5, 1941, a motion was passed authorizing the president to appoint a committee to work on a project which would culminate in a bulletin on the geology of Dallas County, Texas, to be in printed form prior to the annual meeting of the American Association for the Advancement of Science to be held in Dallas, Texas from December 29, 1941 to January 3, 1942. Those members appointed to the general committee were Messrs. C. C. Albritton, Jr. of Southern Methodist University, Robert I. Seale of Schlumberger Well Surveying Corporation, Henry J. Morgan, Jr., of Atlantic Refining Company, John W. Clark of Magnolia Petroleum Company, and John Gillin of National Geophysical Company. At the same time, an editorial committee composed of L. W. MacNaughton, C. C. Albritton, and W. G. Meyer was formed. Dr. Albritton consented to serve as chairman of the general committee and it was mainly through his unselfish efforts that the bulletin was completed within the few months available

    University of Minnesota Ph.D. dissertation. August 2020. Major: Mathematics. Advisor: Vladimir Sverak. 1 computer file (PDF); ii, 158 pages.For better or for worse, our current understanding of the Navier-Stokes regularity problem is intimately connected with certain dimensionless quantities known as critical norms. In this thesis, we concern ourselves with one of the most basic questions about Navier-Stokes regularity: How must the critical norms behave at a potential Navier-Stokes singularity? In Chapter 2, we give a broad overview of the Navier-Stokes theory necessary to answer this question. This chapter is suitable for newcomers to the field. Next, we present two of our published papers [4,5] which answer this question in the context of homogeneous Besov spaces. In Chapter 3, we demonstrate that the critical Besov norms u(,t)B˙p,q1+3/p(R3)\| u(\cdot,t) \|_{\dot B^{-1+3/p}_{p,q}(\R^3)}, p,q(3,+)p,q \in (3,+\infty), must tend to infinity at a potential singularity. Our proof has been streamlined from the published version [4]. In Chapter 4 (joint work with Tobias Barker), we develop a framework of global weak Besov solutions with initial data belonging to B˙p,1+3/p(R3)\dot B^{-1+3/p}_{p,\infty}(\R^3), p(3,+)p \in (3,+\infty). To illustrate this framework, we provide applications to blow-up criteria, minimal blow-up initial data, and forward self-similar solutions.

    We construct non-unique Leray solutions of the forced Navier-Stokes equations in bounded domains via gluing methods. This demonstrates a certain locality and robustness of the non-uniqueness discovered by the authors in [1]
