x_{1} is a mathematical object for/to which operator x_{2} is defined/may be applied when under conditions x_{3} under definition (of operator)/standard/type x_{4}

The result is unimportant. Mathematical objects cannot really do anything nor can they experience anything, and they are not altered, so "kakne" does not really work. x_{2} may be a "mau'au"-"zai'ai"-quoted operator (possibly with some of its terbri filled). x_{3} determines when (example: for which points z in the domain set) (x_{2 (x} makes sense/is defined. x_{4} can be a macro which really is a name of a type of such operator (x_{2} represents the class, x_{4} denotes the specific realization), the name being associated with all of the conditions/rules/descriptions necessary. "Differintegrable (according to some definition or type of differintegral operator named x_{4})": ~"faukne be lo salri co'e" (where x_{3} will be the set upon which
x_{1} is differintegrable and x_{4} can be words like "partial", "directional", "vectorial", "total", "Riemann", "Lebesgue", vel sim.).
