【摘要】 首先给出边值问题的条件，然后讨论抛物算子Ｌｕ与Ｌ１ｕ的某些性质，给出问题Ｄ与问题Ｎ的解的先验估计，最后利用参数开拓法和Ｓｃｈａｕｄｅｒ不动点定理证明两类边值问题的可解性。更多还原

【Abstract】 The conditions of boundary value problem are first given.Then some properties of parabolic operators Lu and L1u are discussed,and the prior estimates of solutions for problem D and problem N are given.Finally we prove the solvability of two kinds of boundary value problems by using the method of parameter extension and Schauder fixedpoint theorem.更多还原
