Abstract  We borrow the general idea of renormalizationgroup equations (RGEs) to understand how neutrino masses and flavor mixing parameters evolve when neutrinos propagate in a medium, highlighting a meaningful possibility that the genuine flavor quantities in vacuum can be extrapolated from their mattercorrected counterparts to be measured in some realistic neutrino oscillation experiments. Taking the matter parameter a 2 root 2G(F)N(e)E to be an arbitrary scalelike variable with Ne being the net electron number density and E being the neutrino beam energy, we derive a complete set of differential equations for the effective neutrino mixing matrix V and the effective neutrino masses (m)overtilde(i)(for i = 1, 2, 3). Given the standard parametrization of V, the RGEs for {(theta)overtilde(12), (theta)overtilde(13), (theta)overtilde(2)(3), (delta)overtilde} in matter are formulated for the first time. We demonstrate some useful differential invariants which retain the same form from vacuum to matter, including the wellknown Naumov and Toshev relations. The RGEs of the partial mutau asymmetries, the offdiagonal asymmetries and the sides of unitarity triangles of V are also obtained as a byproduct.
