Let u be a super-biharmonic function, that is, Δ2u≥ 0, on the unit disc D in the complex plane, satisfying certain conditions. Then it has been shown that u has a representation analogous to the Poisson-Jensen representation for subharmonic functions on D. In the same vein, it is shown here that a function u on any Green domain Ω in a Riemannian manifold(More)
Tissue calcification is a common complication in patients on continuous hemodialysis (HD) for chronic renal failure; however, severe calcification is unusual. Three distinct clinical types of extraosseous calcifications are found in uremic patients: vascular calcification, periarticular (tumoral) calcification, and visceral calcification (heart, lung, and(More)
