  3. Stability constants of complexes - Wikipedia

    en.wikipedia.org/wiki/Stability_constants_of...

    The stability constant databases [8] [9] can be very useful in finding published stability constant values for related complexes. In some simple cases the calculations can be done in a spreadsheet. [35] Otherwise, the calculations are performed with the aid of a general-purpose computer programs. The most frequently used programs are:

  4. Cation-anion radius ratio - Wikipedia

    en.wikipedia.org/wiki/Cation-anion_radius_ratio

    At the stability limit the cation is touching all the anions and the anions are just touching at their edges. For radius ratios greater than the critical ratius ratio, the structure is expected to be stable. The rule is not obeyed for all compounds. By one estimate, the crystal structure can only be guessed about 2/3 of the time. [3]

  5. Structural stability - Wikipedia

    en.wikipedia.org/wiki/Structural_stability

    Ideas of structural stability were taken up by Stephen Smale and his school in the 1960s in the context of hyperbolic dynamics. Earlier, Marston Morse and Hassler Whitney initiated and René Thom developed a parallel theory of stability for differentiable maps, which forms a key part of singularity theory. Thom envisaged applications of this ...

  6. Numerical stability - Wikipedia

    en.wikipedia.org/wiki/Numerical_stability

    Numerical diffusion is a mathematical term which ensures that roundoff and other errors in the calculation get spread out and do not add up to cause the calculation to "blow up". Von Neumann stability analysis is a commonly used procedure for the stability analysis of finite difference schemes as applied to linear partial differential equations ...
