with its $L^{p}(U)$-norm ($U$ is an $n$-dimensional domain that contains $S$). On the basis of these inequalities, we propose a correct definition of the flow through the surface $S$ of a discontinuous solenoidal vector field $f \in L^{p}(U)$ (or, more
precisely, of the class of vector fields that are equal almost everywhere with respect to the Lebesque measure).}, number={8}, journal={Ukrainsâ€™kyi Matematychnyi Zhurnal}, author={Noarov, A. I.}, year={2019}, month={Aug.}, pages={1141-1149} }
