Relativistic laplacian?

]]>Me!

]]>The content of the Varopolos-Carne inequality is a bound that works for any Cayley graph?

The VC inequality in the case of the Integers can be proven using the DeMoivre-Laplace limit theorem. Or using the the entropy formula.

]]>For what it’s worth, I did compute that solutions to the discretised wave equation are critical points for the Lagrangian

but it is not obvious to me how to adapt this Lagrangian to a wave map or Yang-Mills setting.
