Abstract:

Suppose K(x,y) satisfies K(x,y)=K(y,x) and K(tx,ty)=tλK(x,y).Define the singular integral operator T as T(f)(y)=∫+∞0K(x,y)f(x)dx,y∈(0,+∞).Sufficient conditions guaranteeing the norm of T are obtained.Some new integral inequalities are proved from these results.

Key words: symmetric homogeneous kernel, singular integral operator, norm, bounded operator
