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 ...

Boundary value problems for degenerate elliptic differential equations constitute a challenging and vibrant area of mathematical analysis. These problems involve differential operators whose ...
