On blow-up "twistors" for the Navier--Stokes equations in $R^3$: a view from reaction-diffusion theory

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/217608Various formal blow-up scenarious for the Navier--Stokes equaitons in 3D are discussed. A particular interest is payed to "twistor mechanisms" based on angular logarithmic blow-up travelling waves, and to a formation of "blow-up tornado" about the singular stationary Slezkin--Landau solutions (1934--44) of a submerged jet. A survey on various related aspects of singularity analysis for nonlinear parabolic PDEs is enclosed.111 pages, 3 figuresAnalysis of PDEs35K55, 35K40, 35K65On blow-up "twistors" for the Navier--Stokes equations in $R^3$: a view from reaction-diffusion theorytext
