We construct the evolution in two limiting cases applied to the tidal charge. In the first case we assume b = const during the evolution, in the second one we assume that the dimensionless tidal charge beta b/M-2 = const. For positive values of the tidal charge the evolution is equivalent to the case of the standard K-N naked singularity under accretion of electrically neutral matter. We demonstrate that counterrotating accretion always converts a K-N naked singularity into an extreme K-N black hole and that the corotating accretion leads to a variety of outcomes. The conversion to an extreme K-N black hole is possible for naked singularity with dimensionless tidal charge beta < 0.25, and beta is an element of (0.25, 1) with sufficiently low spin. In other cases the accretion ends in a transcendental state. For 0.25 < beta < 1 this is a mining unstable K-N naked singularity enabling formally unlimited energy extraction from the naked singularity. In the case of beta > 1, the corotating accretion creates unlimited torodial structure of mater orbiting the naked singularity. Both nonstandard outcomes of the corotating accretion imply a transcendence of such naked singularity due to nonlinear gravitational effects. ER -
