Relativistic wave equations

Sorry to delete that section but it hardly derives anything, and dwells on four-vectors too much. See talk:Relativistic wave equations. M ∧Ŝ c²ħε И_τlk 15:01, 29 May 2016 (UTC)[reply]

No worries, but could you place some info about the construction of RWE's on the page. I think it would be appropriate and informative. The reason I had put emphasis on 4-vectors is that most of the RWE's have an explicit 4-vector in them.

Thanks, John Wilson

I apologize if I seemed pessimistic. The history section in the article does mention how to get to the KG equation by taking the energy-momentum relation and forming the operator equivalent, and Dirac equation by "factorization" or the "square root" of the KG equation which introduces the alpha and beta matrices. The articles on the KG and Dirac equations also have these details. The relativistic e-p relation is the starting point (and its form can be obtained in the framework of SR). Your route of obtaining the equation was not wrong, but for the RWE article it diverted to four vectors and their invariants, a topic which has its own article and is to be assumed for any RQM article. At some point the article should have a Lorentz group representation section which allows the construction of RWEs for particles of any spin.

I noticed you wrote an identical section in four gradient, which I will not delete, but maybe it could be trimmed/rewritten a little to be more on topic.

Anyway, welcome again and hope you enjoy editing. Why not create an account? We could do with more maths/physics editors. M ∧Ŝ c²ħε И_τlk 18:16, 29 May 2016 (UTC)[reply]

Ok, I have created user account SciRealm. I will continue working on the 4-gradient article. SciRealm (talk) 22:47, 29 May 2016 (UTC)[reply]
