This monthly journal, begun in 1950, is devoted entirely to research in pure and applied mathematics, principally to the publication of original papers of moderate length. A section called Shorter ...

On bounded domains $\Omega \subset {\Bbb R}^{2}$ we consider the anisotropic problems u-auxx + u-buyy = p(x, y) in Ω with a, b > 1 and u = ∞ on ∂ Ω and ucuxx + uduyy + q(x, y) = 0 in Ω with c, d ≥ 0 ...

Fourth-order boundary value problems (BVPs) constitute an essential class of differential equations where the highest derivative is of fourth order. These equations arise naturally in the mathematical ...
