2 The collapsing shell
In a two-dimensional space-time we define:
- conformal global coordinates; .
- time and distance to an origin ().
- Localised massless collapsing shell (, ):
- Boundary conditions for :
- Problem calculate for :
where is a constant (Vendrell (1997a)) (The solution depends actually on the
representation of the delta function (eq.3), which is defined here by
, where the function is continuous except possibly at .)
The functions and are left undetermined for
, contrary to the 4-D case (Synge (1957)).
