Corpus analysis for Differentiability
- In this selection, "differentiability" usually appears near the start of the sentence. The average example has 20.9 words, and this corpus slice is mostly made up of statements.
- Around the word, complex, real, non, implies, suppose and class stand out and add context to how "differentiability" is used.
- Recognizable usage signals include assumption of differentiability or even and by their differentiability class. That gives this page its own corpus information beyond isolated example sentences.
- By corpus frequency, "differentiability" sits close to words such as aaronson, abai and abass, which helps place it inside the broader word index.
Example types with differentiability
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
One can classify functions by their differentiability class. (8 words)
Fréchet differentiability is a stronger condition than Gâteaux differentiability. (9 words)
Complex differentiability has much stronger consequences than usual (real) differentiability. (10 words)
For ψ to be a wavelet for the continuous wavelet transform (see there for exact statement), the mother wavelet must satisfy an admissibility criterion (loosely speaking, a kind of half-differentiability) in order to get a stably invertible transform. (39 words)
The first step is to substitute for g(a + h) using the definition of differentiability of g at a: : The next step is to use the definition of differentiability of f at g(a). (34 words)

Example sentences (14)
Complex differentiability has much stronger consequences than usual (real) differentiability.
Finally, since differentiability implies continuity, the contrapositive states discontinuity implies non-differentiability.
Fréchet differentiability is a stronger condition than Gâteaux differentiability.
The first step is to substitute for g(a + h) using the definition of differentiability of g at a: : The next step is to use the definition of differentiability of f at g(a).
The quasi-derivative is another generalization of directional derivative that implies a stronger condition than Gâteaux differentiability, but a weaker condition than Fréchet differentiability.
Axiomatic approach Richard T. Cox showed that Bayesian updating follows from several axioms, including two functional equations and a hypothesis of differentiability.
Complex differentiability Suppose that : is a function of a complex number z. Then the complex derivative of f at a point z 0 is defined by : provided this limit exists.
Corollary A simple but very useful consequence of L'Hopital's rule is a well-known criterion for differentiability.
For ψ to be a wavelet for the continuous wavelet transform (see there for exact statement), the mother wavelet must satisfy an admissibility criterion (loosely speaking, a kind of half-differentiability) in order to get a stably invertible transform.
One can classify functions by their differentiability class.
Relation to differentiability and integrability Every differentiable function : is continuous, as can be shown.
The assumption of differentiability or even continuity is controversial; Halpern found a counterexample based on his observation that the Boolean algebra of statements may be finite.
The sequence with converges pointwise but not uniformly: : In this example one can easily see that pointwise convergence does not preserve differentiability or continuity.
The sole existence of partial derivatives satisfying the Cauchy–Riemann equations is not enough to ensure complex differentiability at that point.
