In this paper, the boundedness of a large class of sublinear commutator operators $T_{b}$ generated by a Calderón-Zygmund type operator on a generalized weighted Morrey spaces $M_{p,\varphi }(w)$ with the weight function $w$ belonging to Muckenhoupt's class $A_{p}$ is studied. When $1<p<\infty $ and $b \in {\rm BMO}$, sufficient conditions on the pair $(\varphi _1,\varphi _2)$ which ensure the boundedness of the operator $T_{b}$ from $M_{p,\varphi _1}(w)$ to $M_{p,\varphi _2}(w)$ are found. In all cases the conditions for the boundedness of $T_{b}$ are given in terms of Zygmund-type integral inequalities on $(\varphi _1,\varphi _2)$, which do not require any assumption on monotonicity of $\varphi _1(x,r)$, $\varphi _2(x,r)$ in $r$. Then these results are applied to several particular operators such as the pseudo-differential operators, Littlewood-Paley operator, Marcinkiewicz operator and Bochner-Riesz operator.
Marian devotion has represented until today crucial aspect of Christian, especially Catholic, spirituality. Its extraordinary flourishing took plače in the seventeenth and eighteenth centuries, when Pietas Mariana became an imprescindible component of Baroque religiousness. The vigour of Baroque Marian devotion brought about not only the veneration of statues and pictures, but also the reintroduction of pilgrimages and the building of Marian pilgrimage sites throughout the land. One of the most influential Catholic orders that contributed in an important degree to development and spreading of Marian devotion was the Society of Jesus. Aside of their educational and pastora! activities, the Jesuits served as custodians of important Marian pilgrimage sites, as was also the case of the residence in Golčův Jeníkov, where they remained in the years 1657-1773. Throughout this time, they constructed Marian pilgrimage site of regional importance where religious brotherhood had been established and where Loretan devotion had been spread. The everyday life of the residence brought about many activities, among them the organization of festivals along the lines of Baroque ostentatiousness and regular radius of pilgrimages.
