TY - JOUR T1 - Weak Solutions of Second Order Parabolic Equations in Noncylindrical Domains AU - Yong Jiongmin JO - Journal of Partial Differential Equations VL - 2 SP - 76 EP - 86 PY - 1989 DA - 1989/02 SN - 2 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/jpde/5828.html KW - AB - Penalization method is used to get the existence of the weak solutions or parabolic equations in noncylindrical domains. The asympcotic decay and the existence and uniqueness of the periodic solutions are obtained as well.
