Removability of singularities of \(A\)-harmonic functions.
The main result of this paper consists in three theorems. The first two theorems state new Caccioppoli-type estimates for the second order quasilinear partial differential equations. The third one -- removability theorem -- identifies removable singularities of \(A\)-harmonic functions making use of the estimates derived in the previous two theorems.
