Within mathematics regarding differential equations, L-stability is a special case of A-stability, a property of Runge–Kutta methods for solving ordinary differential equations. A method is L-stable if it is A-stable and () as , where is the stability function of the method (the stability function of a Runge–Kutta method is a rational ...
In mathematics, stability theory addresses the stability of solutions of differential equations and of trajectories of dynamical systems under small perturbations of initial conditions. The heat equation , for example, is a stable partial differential equation because small perturbations of initial data lead to small variations in temperature ...
The metacentric height is an approximation for the vessel stability at a small angle (0-15 degrees) of heel. Beyond that range, the stability of the vessel is dominated by what is known as a righting moment. Depending on the geometry of the hull, naval architects must iteratively calculate the center of buoyancy at increasing angles of heel.

For = and =, the distribution is a Landau distribution (L) which has a specific usage in physics under this name. For α = 3 / 2 {\displaystyle \alpha =3/2} and β = 0 {\displaystyle \beta =0} the distribution reduces to a Holtsmark distribution with scale parameter c and shift parameter μ .
where g is the gravitational acceleration, is the thermal expansion coefficient, T hot is the hot wall temperature, T ref is the reference temperature, L is the characteristic length, and V is the characteristic velocity. The Richardson number can also be expressed by using a combination of the Grashof number and Reynolds number,
This formula was derived in 1744 by the Swiss mathematician Leonhard Euler. [2] The column will remain straight for loads less than the critical load. The critical load is the greatest load that will not cause lateral deflection (buckling). For loads greater than the critical load, the column will deflect laterally.
