In algebraic geometry, a non singular point of an algebraic curve is an inflection point if and only if the intersection number of the tangent line and the curve (at the point of tangency) is greater than 2. The main motivation of this different definition, is that otherwise the set of the inflection points of a curve would not be an algebraic set.
The term chromatic inflection (alternatively spelt inflexion) is used in two senses: Alteration of a note that makes it (or the harmony that includes it) chromatic rather than diatonic. [36] Melodic movement between a diatonic note and a chromatically altered variant (from C to C ♯ in G major, or vice versa, for example). [37]
Inflection (or inflexion), is the modification of a word to express grammatical information. Inflection or inflexion may also refer to: Inflection point, a point at which a curve changes from being concave to convex, or vice versa; Chromatic inflection, alteration of a musical note that makes it chromatic
Inflection of the Scottish Gaelic lexeme for 'dog', which is cù for singular, chù for dual with the number dà ('two'), and coin for plural. In linguistic morphology, inflection (less commonly, inflexion) is a process of word formation [1] in which a word is modified to express different grammatical categories such as tense, case, voice, aspect, person, number, gender, mood, animacy, and ...
Nonconcatenative morphology, also called discontinuous morphology and introflection, is a form of word formation and inflection in which the root is modified and which does not involve stringing morphemes together sequentially. [1]
Morphological typology is a way of classifying the languages of the world that groups languages according to their common morphological structures. The field organizes languages on the basis of how those languages form words by combining morphemes.
In the strict sense of the term "uninflected", only invariable words are uninflected, but in broader linguistic usage, these terms are extended to be inflectable words that appear in their basic form. For example, English nouns are said to be uninflected in the singular, while they show inflection in the plural (represented by the affix -s/-es).
A saddle point (in red) on the graph of z = x 2 − y 2 (hyperbolic paraboloid). In mathematics, a saddle point or minimax point [1] is a point on the surface of the graph of a function where the slopes (derivatives) in orthogonal directions are all zero (a critical point), but which is not a local extremum of the function.
