Lower Bounds for Advection-Diffusion Equations: An Exploration with AI-Generated Proofs
A new paper explores lower bounds for advection-diffusion equations using AI-generated proofs. The research presents explicit lower bounds in various settings, demonstrating the capabilities of AI in producing rigorous mathematical results. This study contributes to the field of analysis of partial differential equations and artificial intelligence.
- ▪The paper establishes explicit lower bounds for advection-diffusion equations in three different settings.
- ▪It includes a polynomial bound for inviscid shears and a uniform positive lower bound on the mixing scale for diffusive shears.
- ▪The proofs were generated entirely by an AI system called QED without human intervention.

All constants are explicit in the data.
