Fist and second order constraints in a system?

AI Thread Summary
Understanding first and second class constraints in systems can be challenging, as evidenced by the difficulty experienced with Goldstein's work. Dirac's lectures have been helpful, but additional resources are sought for better visualization and problem-solving. A recommended book is "Lectures on Constrained Systems" by Ghanashyam Date, which is available on arXiv, although it may not cover all requested topics comprehensively. Further exploration of constraint theory is encouraged to enhance understanding. Accessing diverse materials can significantly aid in grasping these complex concepts.

I've tried with Goldstein but no luck, i need to understand how the constraint, especially the second class act on system, i also referred Dirac's lecture, they were quiet good, but if u can suggest some books which can help me learn first and second class constraints with examples and problems that will help me visualize the concept it will really help a lot...thanks in advance

"Lectures on Constrained Systems" Ghanashyam Date. I think you can get it on arxiv. It has some stuff, but maybe not enough for what your asking for.
 
Thread 'Gauss' law seems to imply instantaneous electric field'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
