Что (кто) такое quadratically summable function - определение

Locally integrable; Local integrability; Locally summable function

Square-integrable function         
FUNCTION WHOSE SQUARED ABSOLUTE VALUE HAS FINITE INTEGRAL
Square-integrable; Square integrable; Square integrable function; L2 space; L2 Space; L2-space; L2-function; L2-inner product; L^2; Quadratic integrability; Quadratically integrable; Square-summable function; Square integrability; Quadratically integrable function; L² space; Square-integrable functions; Square-integrability
In mathematics, a square-integrable function, also called a quadratically integrable function or L^2 function or square-summable function, is a real- or complex-valued measurable function for which the integral of the square of the absolute value is finite. Thus, square-integrability on the real line (-\infty,+\infty) is defined as follows.

Locally integrable function

In mathematics, a locally integrable function (sometimes also called locally summable function) is a function which is integrable (so its integral is finite) on every compact subset of its domain of definition. The importance of such functions lies in the fact that their function space is similar to Lp spaces, but its members are not required to satisfy any growth restriction on their behavior at the boundary of their domain (at infinity if the domain is unbounded): in other words, locally integrable functions can grow arbitrarily fast at the domain boundary, but are still manageable in a way similar to ordinary integrable functions.
