Özet
We consider the generalized shift operator, associated with the Laplace-Bessel differential operator Delta(B) = Sigma(n)(i=1) partial derivative(2)/partial derivative x(i)(2) + Sigma(k)(i=1) gamma(i)/x(i) partial derivative/partial derivative x(i). The maximal operator M-gamma (B-maximal operator) and the Riesz potential I-gamma(alpha) (B-Riesz potential), associated with the generalized shift operator are investigated. At first, we prove that the B-maximal operator M-gamma is bounded from the B-Morrey space L-p,L-lambda,L-gamma to L-p,L-lambda,L-gamma for all 1 < p < infinity and 0 <= lambda < n + vertical bar gamma vertical bar. We prove that the B-Riesz potential I-gamma(alpha), 0 < alpha < vertical bar gamma vertical bar is bounded from the B-Morrey space L-p,L-lambda,L-gamma to L-q,L-lambda,L-gamma if and only if alpha/(n+vertical bar gamma vertical bar - lambda) = 1/p - 1/q, 1 < p < (n + vertical bar gamma vertical bar - lambda)/alpha. Also we prove that the B-Riesz potential I-gamma(alpha) is bounded from the B-Morrey space L-1,L-lambda,L-gamma to the weak B-Morrey space WLq,lambda,gamma if and only if alpha/(n + vertical bar gamma vertical bar - lambda) = 1 - 1/q.
