Add to ORKG<正> A class of semilinear ω-periodic parabolic systems is studied. First, by combining the degree theory with upper-lower solution method, the general principle which is used for proving that the system has at least two positive ω-periodic solutions is established. Then some applications are given.国家教委基金,国家自然科学基金中文核心期刊要目总览(PKU)中国科学引文数据库(CSCD)03367-380
