Foundations of Ancient Solutions to Navier-Stokes Equations

Exploring the mathematical behavior of fluid dynamics requires a firm grasp of partial differential equations and their long-term trajectories. This text-based course introduces you to the analysis of Navier-Stokes equations, focusing on ancient solutions and their connection to global well-posedness in boundary value problems. You will build a structured understanding of fundamental PDE concepts, modern analytical methods, and the mathematical formulations governing incompressible flows in full and half spaces. What you'll learn: - Understand core definitions and governing principles of the Navier-Stokes equations - Analyze the concept of ancient solutions existing backwards in time - Study initial boundary value problem formulations in space and half-space domains - Explore mathematical criteria for regularity, singularity formation, and well-posedness - Apply modern energy methods and scaling techniques used in PDE analysis - Examine asymptotic behavior and classification strategies for hydrodynamic solutions The course begins with foundational terminology and functional analysis tools before progressing through step-by-step theoretical explanations and written analytical examples. This course is designed for mathematics and physics students or curious analytical learners seeking a clear, accessible entry point into modern partial differential equations.
