). The quadratic formula

gives the roots of any quadratic equation in terms of its coefficients a, b, and c. The expression b2−4ac is called the discriminant and vanishes when the two roots coincide. If a, b, and c are real and the discriminant is not less than zero, the roots are real.

In this case, pair-wise Gibbs potentials are selected as a minimum of a finite set of quadratic functions and an efficient optimization procedure is proposed for the Blake and Zisserman function, which is often used in edge-preserving procedures.

Since we, in this paper, deal with the improving of the algorithm to determine whether a quadratic eigenvalue problem is definite or not, let us briefly summarize what has been done so far in the literature up to this point.

Then, a proof is provided to demonstrate that price equilibrium is not guaranteed for every possible location of firms under convex/ concave strictly linear quadratic transportation costs.
A multilevel LGM approach was used that estimates the initial levels of the change trajectories of the studied variables (Intercept) and a linear, quadratic, and cubic growth over time in these trajectories (Slope, Quadratic, and Cubic factors) and separately considers average levels in these trajectories estimated on the full sample from the inter-individual variability around these average levels (Duncan et al.
