This paper organizes some important results in the theory of homogeneous Lagrangians. One can construct a canonical Lagrangian form which is closed exactly when the Lagrangian is null. In the case of first-order homogeneity the variation integrals are parameter-independent, and the use of special (affine) coordinates leads to the result that the ...

A nonapplicable null appears in a relation whenever the value of the corresponding attribute does not exist. In order to evaluate a query on a relation r involving such null values, the information contained in r is represented by a set of null-free instances, then the query on r - expressed in a user-friendly query language (Generalized Relational ...

The null divergence factor [PDF]
Let (P,Q) be a C1 vectorfield defined in a open subset U ⊂ R2. We call a null divergence factor a C1 solution V (x, y) of the equation P ∂V ∂x + Q∂V ∂y = ∂P ∂x + ∂Q ∂y V . In previous works it has been shown that this function plays a fundamental role in the problem of the center and in the determination of the limit cycles.
