cmavo unary mathematical operator: absolute value/norm a.


cu'a zei fancu
zeilujvo f_{1} is an absolute value function from domain f_{2} to range f_{3}. Defined by: f(x) = abs(x)

lujvo x_{1} is the absolute value/norm of x_{2}. See also cu'a

experimental cmavo binary mathematical operator: vector norm/magnitude of vector a in structure (normed vector space) b Contextless default for b: Euclidean normed vector space over the reals or complexes; in relativity, without context, the default interpretation for a fourvector is the Minkoski magnitude. b determines the meaning of the norm. Accompanies and clarifies cu'a.

experimental cmavo mekso unary operator: cardinality (#,  ) Usually should be reserved for use on sets; if applied to group, it is the cardinality of the underlying set (Which is the order of the group) but it should probably not be applied to an element of a group. Application to a graph is ambiguous: is it the number of vertices or edges, or both, or neither, (if it defined at all)? For a set, each unique heretofore not counted element increments the running subtotal by 1 if the set is countable (small infinite or finite). See: cu'a, zilkancu, nilzilcmi, gu'au'i.

experimental cmavo mekso operator, variable arity  algebraic structure order of X1; OR: order of/(size of) period of element X1 in algebraic structure X2 under operator/of type X3 If applied to an algebraic structure (such as a group) it gives the order thereof (which, for a group, is the cardinality of the underlying set). If applied to an element of an algebraic structure, one has the options to specify the structure in which its order is being considered and/or the operator with respect to which its order is being considered (for example, in a given ring, an elements additive order is usually not its multiplicative order), although either of these made remain vague and be inferred from context; order is the smallest nonnegative number of applications of the operator needed to be applied (in composition) to the original element in order for it to result in the identity element of the structure (thus, order is not always finite or even defined).
