  2. Function composition - Wikipedia

    en.wikipedia.org/wiki/Function_composition

    That is, if f, g, and h are composable, then f ∘ (g ∘ h) = (fg) ∘ h. [3] Since the parentheses do not change the result, they are generally omitted. In a strict sense, the composition gf is only meaningful if the codomain of f equals the domain of g ; in a wider sense, it is sufficient that the former be an improper subset of ...

    en.wikipedia.org/wiki/Closed_graph_property

    Observation: If g : S → Y is a function and G is the canonical set-valued function induced by g (i.e. G : S → 2 Y is defined by G(s) := { g(s) } for every s ∈ S) then since Gr g = Gr G, g has a closed (resp. sequentially closed, open, sequentially open) graph in X × Y if and only if the same is true of G.

    Language scripts or transcription schemes that use the dot above a letter as a diacritical mark: In some forms of Arabic romanization, ġ stands for ghayn (غ).; The Latin orthography for Chechen includes ċ, ç̇, ġ, q̇ and ẋ, corresponding to Cyrillic цӏ, чӏ, гӏ, къ and хь and representing /tsʼ/, /t͡ʃʼ/, /ɣ/, /qʼ/ and /ħ/ respectively.

  7. Dot product representation of a graph - Wikipedia

    en.wikipedia.org/wiki/Dot_product_representation...

    Let G be a graph with vertex set V. Let F be a field, and f a function from V to F k such that xy is an edge of G if and only if f(x)·f(y) ≥ t. This is the dot product representation of G. The number t is called the dot product threshold, and the smallest possible value of k is called the dot product dimension. [1]

  8. Seven-segment display character representations - Wikipedia

    en.wikipedia.org/wiki/Seven-segment_display...

    The following phrases come from a portable media player's seven-segment display. They give a good illustration of an application where a seven-segment display may be sufficient for displaying letters, since the relevant messages are neither critical nor in any significant risk of being misunderstood, much due to the limited number and rigid domain specificity of the messages.

    C: — First hard disk drive partition. D: to Z: — Other disk partitions get labeled here. Windows assigns the next free drive letter to the next drive it encounters while enumerating the disk drives on the system. Drives can be partitioned, thereby creating more drive letters.
