The Cayley Cubic and Differential Equations [PDF]
We define Cayley structures as a field of Cayley's ruled cubic surfaces over a four dimensional manifold and motivate their study by showing their similarity to indefinite conformal structures and their link to differential equations. In particular, for Cayley structures an extension of certain notions defined for indefinite conformal structures in ...

The cubic vortical Whitham equation [PDF]
The cubic-vortical Whitham equation is a model for wave motion on a vertically sheared current of constant vorticity in a shallow inviscid fluid. It generalizes the classical Whitham equation by allowing constant vorticity and by adding a cubic nonlinear term.

A Complete Review of the General Quartic Equation with Real Coefficients and Multiple Roots
This paper presents a general analysis of all the quartic equations with real coefficients and multiple roots; this analysis revealed some unknown formulae to solve each kind of these equations and some precisions about the relation between these ones ...

A modelling approach to the choice of the equations of state of analogues of three serie [PDF]
Within the framework of a simple molecular thermodynamic model, the problems of comparing the equations of state and the choice of analogues in three sets are analyzed: equations based on the model of interacting point centers, van der Waals type ...

In order to propose a deeper analysis of the general quartic equation with real coefficients, the analytical solutions for all cubic and quartic equations were reviewed here; then, it was found that there can only be one form of the resolvent cubic that ...

Diagonal cubic equations. II [PDF]
[For part II, Acta Arith (to appear) see the preceding review.] Given positive integers \(\lambda _ 1,...,\lambda _ s\) with \(s=8\) or 9 it is known that the equation \(\lambda _ 1x\quad 3_ 1+...+\lambda _ sx\quad 3_ s=0\) is soluble in integers with \[ 0\quad

A generalized computation procedure for Ramanujan-type identities and cubic Shevelev sum [PDF]
A generalized Computation procedure for construction of the Ramanujan-type from a given general cubic equation and a cosine Ramanujan-type identity is developed from detailed analyses of the properties of Ramanujan-type cubic equations.

Generating functions for a lattice path model introduced by Deutsch
The lattice path model suggested by E. Deutsch is derived from ordinary Dyck paths, but with additional down-steps of size −3, −5, −7, . . . . For such paths, we find the generating functions of them, according to length, ending at level i, both, when ...
