For an operator (e.g. More...
|virtual unsigned int||num_particles () const =0|
|virtual unsigned int||num_functions (unsigned int i) const =0|
|number of functions for particle i |
|virtual int||perm_symm (unsigned int i) const =0|
|+1 corresponds to hermitian, -1 to antihermitian, 0 to nonhermitian |
|virtual int||perm_symm (unsigned int i, unsigned int j) const =0|
|Symmetry with respect to permutation of particles i and j. |
For an operator (e.g.
<ij|1/r12|kl> ) OperatorDescr gives basic properties with respect to permutations, etc.
