Abstract
Let P and Q be two polynomials without constant term. Assume that the operator B P,Q ( f ,g)(x) = f (x-P(t))g(x-Q(t)) dt /t is bounded from L p1 ×L p2 into L r , p1, p2 ∈ (1,∞), 1/ p1 + 1/ p2 = 1/r . It is proved that if P′ (t) > 0 for all t ≠= 0, then r ≥ d/ d+1 . Here d is the correlation degree of P and Q which is defined as the largest multiplicity of non-zero real roots of P′ -Q′.
