Motivated by a classical result of Finn and Osserman (J Anal Math 343(12):351–364, 1964), who proved that the Jenkins–Serrin graph over square inscribed in unit disk is extremal for Gaussian curvature point O (so-called centre) minimal graphs above center 0 disk, provided tangent plane horizontal, we ask answer to question concerned "second derivative" such its at zero. We prove extremals are c...

Purpose: Given the high prevalence of varus malalignment of the knee and the consequences of walking on different surfaces on this malalignment, the aim of the present study was to investigate the effect of walking inclination on knee angle in the frontal plane of patients with varus malalignment. Methods: 18 male subjects with varus malalignment classified at grade 3 bowleg, within the a...

Zero point problems of the sum of two monotone mappings and fixed point problems of a strictly pseudocontractive mapping are investigated‎. ‎A strong convergence theorem for the common solutions of the problems is established in the framework of Hilbert spaces‎.
