Correction: Buckling of swelling gels (The European Physical Journal E, (2006), 20, 2, (119-124), 10.1140/epje/i2005-10124-5)

We report here an error in an Equation in the referenced article that has an impact on a Figure, although overall conclusions of the article remain unaffected. The correct version of Eq. (15) is (Formula presented.) where the prefactor of the second term in the brackets has been corrected to 1/r. Figure 7 should be replaced by the figure on the right, where the theoretical line has been modified according to numerical solutions of the problem with the correct Eq. (15). The general trends are unaffected, though the discrepancy between experiments and theory is slightly larger than what was initially reported. (Figure presented.) We apologise for the inconvenience this error may have caused. We are grateful to Prof. Hiro Tanaka (University of Hyogo) for spotting and correcting this error.
