The starting point for all the equations you need to enter in the
program is the potential for your model, which in turn defines your
field content. So the first expression you need to derive in program
variables is the potential itself. The program potential is defined as
|
(4.8) |
where is the physical potential of your model, expressed in terms
of program fields. This is easiest to illustrate with an example, so
continuing with the TWOFLDLAMBDA model we have
|
(4.9) |
so
|
(4.10) |
and
|
(4.11) |
Because the coupling constants and appear in the program
potential only in the combination
we choose for
convenience to define a new variable
.
