  1. The study of degenerate elliptic equations can be traced back to 1910 ' s, first appeared in picone ' s thesis. after half century ' s development in this field, o. a. oleinik and e. v. radkeic, published their classic monograph second order equations with nonnegative characteristic form in 1971

    而這類方程的特徵形式在所研究的區域上是變號的，即在有的子區域上非負，而在其餘的子區域上非正。
  2. Normally, we try to get the dual form of mathematical programming to change primary programming, which is difficult to be solved into its dual programming, which is easily to be solved. after we had got the dual form of two programming, we found their form were very simply because they had only nonnegative and linear constraints

    通常，我們求出規劃問題的對偶形式是希望將不易求解的原問題轉化為易於求解的對偶問題，在分別得到這兩類問題的對偶形式后，發現其形式簡單，只帶有非負約束和線性約束。
  3. Considering enough the property of the equa - tion, we prove existence of absorbing set of the solution in h ~ ( 1 ) by the method of changeing the higher order nonlinear term as nonnegative guadratic form and prove existence of absorbing set of the solution in h ~ ( 2 ) by the method of linear combining of energy inequality and multiform classical inequality

    我們充分考慮方程的特點，將高階非線性項化為一非負定二次型使得解在h ~ 1中的吸收集的存在性得以證明。通過能量估計的巧妙組合以及多種形式的不等式進行精細的估計以獲得h 「的吸收集的存在性
  4. The collection of all ect splines of order n forms a linear space called a space of ect splines, over which if each connection matrix is nonsingular, lower triangular and totally positive, there exist ect b splines having nonnegative, form a partition of unity, and minimal compact supports
