 If "S" is a distribution in "U", then define a map formula_203 by formula_204 and if "T" is a distribution in "V" then define a map formula_205 by formula_206.Note that formula_207 and formula_208.The distribution "S" on "U" thus produces a continuous linear map formula_209 defined by formula_210, where if in addition the support of "S" is compact then it also induces a continuous linear map of formula_211.
