I'm a undergraduate (sophomore) physics student who wants to study The Classical Theory of Fields by Landau & Lifshitz. What subject are required for studying this book/topic?

I have already studied

  • classical dynamics (Fowles, Landau)

  • electrodynamics (not whole topics, just electrostatics, magnetostatics and E or M field in matter)

  • quantum mechanics (Griffiths ~ch.4)

  • special relativity

  • statistical mechanics and thermal physics

The mathematics I have studied are

  • calculus

  • differential equations (ordinary and partial)

  • linear algebra

  • variational calculus

  • complex analysis (until the residue theorem)

  • a little about tensors (I'm not studied this detail. I just studied for special relativity)

Are there any other topics which I must learn?

  • $\begingroup$ Probably the most important things are being comfortable with the idea of a field (which it seems you are), and the methods of Lagrangian mechanics (mostly basic variatioa calculus, Noether's theorem, functional differentiation). Other than that, just go for it. $\endgroup$ – Bob Knighton Dec 15 '17 at 19:18
  • $\begingroup$ @BobKnighton Thanks for your comment. According to your advice, I think I can start it. :) $\endgroup$ – Seal Dec 15 '17 at 19:26
  • $\begingroup$ Given this is vol.2 of the course, you should be immensely comfortable with the contents of vol.1, which is “Mechanics”. $\endgroup$ – ZeroTheHero Dec 16 '17 at 6:33
