SOME NECESSARY AND SUFFICIENT CONDITIONS FOR EXISTENCE OF POSITIVE SOLUTIONS FOR THIRD ORDER SINGULAR SUBLINEAR MULTI-POINT BOUNDARY VALUE PROBLEMS被引量：5
《Acta Mathematica Scientia》2014年第6期1795-1810,共16页韦忠礼 
supported by the National Science Foundation of Shandong Province(ZR2009AM004)
We mainly study the existence of positive solutions for the following third order singular multi-point boundary value problem{x^（3）（t） ＋ f（t, x（t）, x′（t）） = 0, 0 〈 t 〈 1,x（0）-∑i=1^m1 αi x（ξi） = 0...

RELATIVE ENTROPY AND LARGE DEVIATIONS UNDER SUBLINEAR EXPECTATIONS被引量：6
《Acta Mathematica Scientia》2012年第5期1826-1834,共9页高付清 徐明周 
supported by the National Natural Science Foundation of China(11171262);the Specialized Research Fund for the Doctoral Program of Higher Education (200804860048)
We give a definition of relative entropy with respect to a sublinear expectation and establish large deviation principle for the empirical measures for independent random variables under the sublinear expectation.

POSITIVE SOLUTIONS OF HIGHER ORDER SUBLINEAR FUNCTIONAL DIFFERENTIAL EQUATIONS
《Acta Mathematica Scientia》1992年第3期337-345,共9页缪益华 
In this paper, we discuss higher order sublinear functional differential equation x(n)(t)+p(t)x(v)(g(t)) =0 t greater-than-or-equal-to t0 where n greater-than-or-equal-to 2, 0
