TY - JOUR T1 - Harmonic Maps and Critical Points of Penalized Energy AU - Chunqin Zhou & Deliang Xu JO - Journal of Partial Differential Equations VL - 2 SP - 111 EP - 126 PY - 2003 DA - 2003/05 SN - 16 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/jpde/5410.html KW - Harmonic map KW - blow-up formula KW - penalized energy AB - We discuss a sequence solutions u_ε for the E-L equations of the penalized energy defined by Chen-Struwe. We show that the blow-up set of u_ε is a H^{m-2} - rectifiable set and its weak limit satisfies a blow-up formula. Consequently, the weak limit will be a stationary harmonic map if and only if the blow-up set is stationary.
