Member Function Documentation

compute()

ProperTimeValue srfm::proper_time::ProperTime::compute ( double  coordinate_time, double  velocity  )

staticnoexcept

Compute ProperTimeValue for a portfolio with given coordinate time and velocity.

Parameters

coordinate_time	Elapsed coordinate time (years or any unit).
velocity	Normalised velocity β = portfolio_vol / max_vol, clamped to [0, BETA_MAX_SAFE].

Returns

ProperTimeValue with tau = t / γ.

Definition at line 37 of file proper_time.cpp.

gamma_factor()

double srfm::proper_time::ProperTime::gamma_factor ( double  velocity )

staticnoexcept

Compute Lorentz factor γ = 1 / √(1 − β²) for a given velocity.

Parameters

velocity

Normalised velocity β ∈ [0, 1).

Definition at line 19 of file proper_time.cpp.

to_velocity()

double srfm::proper_time::ProperTime::to_velocity ( double  portfolio_vol, double  max_vol = DEFAULT_MAX_VOL  )

staticnoexcept

Convert a raw portfolio volatility to normalised velocity β.

Parameters

portfolio_vol	Annualised volatility (e.g. 0.20 = 20 %).
max_vol	Speed-of-light analogue (default 0.50).
