Abstract

We refine the iterated blow-up techniques. This technique, combined with a rigidity result and a specific choice of the kernel projection in the Poincar\'e inequality, might be employed to completely linearize blow-ups along at least one sequence. We show how to implement such argument by applying it to derive affine blow-up limits for BD\mathrm{BD} and BV\mathrm{BV} functions around Cantor points. In doing so we identify a specific subset of points - called totally singular points having blow-ups with completely singular gradient measure Dp=DspD p=D^s p, Ep=Esp\mathcal{E} p=\mathcal{E}^s p - at which such linearization fails.
