KAIZHONG GUAN, JIANHUA SHEN, NECESSARY AND SUFFICIENT CONDITIONS FOR THE OSCILLATION OF A FIRST-ORDER NEUTRAL DIFFERENTIAL EQUATION OF EULER FORM, The Rocky Mountain Journal of Mathematics, Vol. 41, ...

First-order systems are those which can be described by first-order differential equations. A common example is the RC circuit. You will need Adobe Acrobat Reader to ...

This paper develops a least-squares functional that arises from recasting general second-order uniformly elliptic partial differential equations in n = 2 or 3 dimensions as a system of first-order ...
