... Int[(supp f + supp g) c ] and therefore supp(f  g) ⊂ supp f + suppg. • Remark 10. If both f and g have compact support, then fgalso has compact support. However, fgneed not have compact support ... y)g(y)dy =  (x−supp f)∩supp g f(x − y)g(y)dy. If x/∈ supp f +supp g, then (x −supp f)∩supp g = and so (f  g)(x) = 0. Thus (f  g)(x) = 0 a.e. on (supp f + supp g) c . In particular, (f ...
