Marco Di Francesco and Andrea Pascucci

where z = (x, t) ∈ RN×R and 1 ≤ p0 ≤ N. By convenience, hereafter the term “Kolmogorov equation” will be shortened to KE. We assume the following hypotheses: (H.1) the matrix A0 = (aij)i,j=1,...,p0 is symmetric and uniformly positive definite in R p0 : there exists a positive constant μ such that |η| μ ≤ p0 ∑ i,j=1 aij(z)ηiηj ≤ μ|η|, ∀η ∈ R0 , z ∈ R; (1.2) (H.2) the matrix B ≡ (bij) has constan...

Prior to competing in these markets, firms can spy on others in order to increase the quality of their product.

We fully support the author’s view that overweight and insulin resistance, as mediators of renal risk, deserve attention not only in morbidly obese patients with overt insulin resistance, but also in renal patients with less severe obesity. Recent data from our group suggest that the impact of overweight and...
