Stability is the property of a _________(a) partial differential equat

1.	Stability is the property of a _________(a) partial differential equation(b) discretized equation(c) discretization process(d) mathematical modelThe question was asked in homework.I need to ask this question from Discretization Aspects in portion Basic Aspects of Discretization, Grid Generation with Appropriate Transformation of Computational Fluid Dynamics
Answer» RIGHT option is (b) discretized equation To elaborate: STABILITY is not the property of a discretization process; it is the property of the resulting SYSTEM of discretized equation. This can be analysed mathematically for the system. Stability does not EXIST for a partial differential equation or a mathematical model.
