⑴对具mutualist的多种群反应扩散模型的研究(见Math. Biosci. 78 (1986),217--245; J. Math. Anal. Appl. 124 (1987),254-280; J. Partial Differential Equations 7 (1994),264--268).是最早进行这类问题研究的学者之一,有较广泛的国际影响,有关文章被国内外同行广泛引用至今.⑵对具非均匀反应项的反应扩散方程解的渐近性的研究(见Proc. Amer. Math. Soc. 98 (1996),103--108.也见王明新的专著“非线性抛物方程”(科学出版社,1993)).⑶关于反应扩散方程组弱不变区域理论的研究(国家自然科学基金项目“反应扩散方程组弱不变区域的理论与数学生态学模型”,19371017),将不变区域的经典理论与Alikakos和Rothe最大模估计的技巧结合起来,引进了弱不变区域的新概念,并建立有界弱不变区域的判定定理.这一新的理论框架充分利用系统中各个分量之间的相互作用,允许反应项的适度增长性,可容纳相当广泛的(特别是具实际背景的)反应扩散方程组,从而将解的存在性的证明大大简化(见应用数学学报17 (1994),578--584; Proc. Roy. Soc. Edinburgh 130A (2000),1165-1180),得到多位国内外专家的肯定和好评.⑷关于反应扩散方程组中临界增长性的分析研究(国家自然科学基金项目“关于反应扩散方程组临界增长性的分析及其数值模拟”,19871008).主要工作见 Math. Methods Appl. Sci. 22 (1999),43-54(SCI); J. Math. Anal. Appl. 232 (1999),293--311; Nonlinear Anal. 39 (2000),327--340.已引起国内外同行的注意,被多次引用. 得到著名数学家J. Serrin(美国科学院院士)的好评.⑸关于非线性双曲守恒律组广义解的稳定性和唯一性的研究(见 J. Math. Res. Exposition 5 (1985),89--93; Acta Math. Sci. 4 (1984),443--454; Proc. Amer. Math. Soc. 96 (1986),295-296),改进和推广了著名数学家R. DiPerna的重要工作,得到DiPerna本人的充分肯定.为美国“数学评论”(Mathematical Reviews)撰写这些领域的评论150余则. 以下为2000年前以本人为唯一作者的部分工作(限于列举被SCI检索的国外期刊文章).Sining Zheng,A necessary condition for $L^2$ stability of quasilinear conservation laws,Proc.
