Detailed Description

Finite physical couplings used to evaluate the Euclidean action.

Construct instances with make_physical_parameters() so invalid or non-finite coupling combinations are rejected at the API boundary.

friend

Validate physical couplings for three-dimensional action APIs.

Parameters

alpha	Wick-rotation parameter; must be finite and greater than 1/2.
k	Inverse Newton coupling; must be finite.
lambda	Cosmological coupling; must be finite.

Returns

Validated coupling values.

Exceptions

std::invalid_argument	if any coupling is non-finite.
std::domain_error	if alpha is not greater than 1/2.
