Fourier multiplier; Fourier multiplier operator; Marcinkiewicz multiplier theorem; Multiplier theorem; Multiplier operator
In Fourier analysis, a multiplier operator is a type of linear operator, or transformation of functions. These operators act on a function by altering its Fourier transform.

Keynesian multiplier; Spending multiplier; Multiplier Effect
In economics, the fiscal multiplier (not to be confused with the money multiplier) is the ratio of change in national income arising from a change in government spending. More generally, the exogenous spending multiplier is the ratio of change in national income arising from any autonomous change in spending (including private investment spending, consumer spending, government spending, or spending by foreigners on the country's exports).
