Class Documentation¶

template<Z2Group Group = NoConcreteGroup>
class Z2Irrep¶ An IRREP of a Z2 group (in which every element is its own inverse) that may contain symbolic (unevaluated) factors. It is represented as the product of a concrete IRREP of Group and a set of symbols, each of which represents an IRREP that is unknown at the time of code generation.
Public Functions
-
Z2Irrep() = default¶
Creates the totally symmetric IRREP.
-
inline explicit Z2Irrep(std::uint8_t concrete, symbol_container symbols = {})¶
- Parameters:
concrete – Index of the concrete IRREP in Group::names
symbols – The symbolic factors (in any order). As every IRREP is its own inverse, pairs of identical symbols cancel.
- Throws:
Exception – if concrete is out of range or if a symbol is empty, contains a ‘*’ or is the name of one of Group’s IRREPs
-
inline std::uint8_t concrete() const¶
- Returns:
Index of the concrete IRREP in Group::names (interpreted as bitmask)
-
inline const symbol_container &symbols() const¶
- Returns:
The sorted list of (unique) symbols
