Struct PoissonBracket 

pub struct PoissonBracket {
    pub f: String,
    pub g: String,
    pub result: String,
}

The Poisson bracket {f, g} = Σᵢ (∂f/∂qᵢ ∂g/∂pᵢ − ∂f/∂pᵢ ∂g/∂qᵢ).

Fields

f: String

Name of the first function f

g: String

Name of the second function g

result: String

Symbolic result of the bracket

Implementations

impl PoissonBracket

pub fn new() -> Self

Create a Poisson bracket record for functions f and g.

pub fn satisfies_jacobi_identity(&self) -> bool

The Jacobi identity: {{f,g},h} + {{g,h},f} + {{h,f},g} = 0.

pub fn is_derivation(&self) -> bool

The Leibniz rule: {f, gh} = {f,g}h + g{f,h} (bracket is a derivation).

Trait Implementations

impl Default for PoissonBracket

fn default() -> Self

Returns the “default value” for a type.
