Struct ConservedQuantity 

pub struct ConservedQuantity {
    pub name: String,
    pub symmetry: Symmetry,
    pub expression: String,
}

A conserved Noether charge associated to a continuous symmetry.

Fields

name: String

Name of the conserved quantity (e.g., “energy”, “momentum”).

symmetry: Symmetry

The symmetry responsible for conservation.

expression: String

Mathematical expression for the conserved charge.

Implementations

impl ConservedQuantity

pub fn new( name: impl Into<String>, symmetry: Symmetry, expression: impl Into<String>, ) -> Self

Create a new ConservedQuantity.

pub fn is_conserved_on_shell(&self) -> bool

A Noether charge is conserved on-shell (along solutions to the E-L equations).
