  Uncertainties in flavor and mass eigenstates of neutrinos are considered
within the majorization approach. Nontrivial bounds reflect the fact that
neutrinos cannot be simultaneously in flavor and mass eigenstates. As
quantitative measures of uncertainties, both the R\'{e}nyi and Tsallis
entropies are utilized. Within the current amount of experience concerning the
mixing matrix, majorization uncertainty relations need to put values of only
two parameters, viz. $\theta_{12}$ and $\theta_{13}$. That is, the majorization
approach is applicable within the same framework as the Maassen-Uffink relation
recently utilized in this context. We also consider the case of detection
inefficiencies, since it can naturally be incorporated into the entropic
framework. Short comments on applications of entropic uncertainty relations
with quantum memory are given.
