I am currently reading the famous article "Universal Properties of Maps on an Interval" by Collet, Eckmann and Lanford related to the Feigenbaum-Coullet-Tresser universality. I am …
What mathematical treatment is there on the renormalization group flow in a space of Lagrangians?
Looking for good summer schools on quantum field theory (especially renormalization theory) this summer [closed]
I'm a graduate student and I'm looking for summer schools to attend this summer. Anyone have any suggestions? Thanks!
Reading Kontsevich's "Operads and Motives in Deformation Quantization", I was wondering about the state of the many conjectures concerning the Grothendieck-Teichmüller group in cha …
As far as I understand, the RG theory, or functional RG theory is a mathematical tool for moving in the "scale dimension". The tool can be used for calculation of Feigenbaums const …
As I understand it, Lions and DiPerna demonstrated existence and uniqueness for the Boltzmann equation. Moreover, this paper claims that Appropriately scaled families of DiPe …
is it a way to make a function smooth?
