ABSTRACT
The article presents a definition of the concept of higher-order directional derivative of a smooth function. It is then applied to create three simple formulas for the nth derivative of the composition of two functions. These three higher-order chain rules are alternatives to the classical formula of Faa di Bruno. They are less explicit but are much simpler and are not saddled with Diophantine or combinatorial problems.

In the present paper, we consider a mixed boundary value problem for the Laplace equation. The boundary conditions specify the normal derivative on part of the boundary and a directional derivative on the remaining part. The solution is represented by a biorthogonal series. We show that if the...

In the present paper, we consider the Tricomi problem with mixed boundary conditions. One of these conditions specifies a directional derivative with constant inclination angle. We show that the problem is either conditionally solvable or has a unique solution depending on the inclination angle.

Of great importance to management, the computation of trade-offs presents particular difficulties within DEA since the piecewise linear nature of the envelopment surfaces does not allow for unique derivatives at every point. We present a comprehensive framework for analyzing marginal rates, and...
