Order-invariance

WebOrder invariance is frequently used for logic-based approaches in computer science. Order-invariant formulas capture unordered problems of complexity classes and they model the … WebTime-invariance guarantees that the coefficients in Eq. (2) are constants. In certain situations it may be difficult to describe a system with a single differential equation, but a set of lower order coupled differential equations may be more convenient.

WebIn order to prove that Equation (4) deﬁnes H w and φ w up to isometries, we need the following assumption on the space of images. Hypothesis 2.1 We assume that Im(R) is a compact subset of L2(R,{−1,1}), the space of square-integrable functions on Rtaking values in {−1,1}. Using Hypothesis 2.1 we can prove the well-deﬁniteness of φ w.
