On the convexity of functional splines
Computer Aided Geometric Design, 1993We prove the convexity of large classes of functional splines with help of results on quasiconcave and pseudoconcave functions. The method developed for functional splines can also be used for smooth approximations of convex polyhedrons and some other convex surfaces.

Mathematical Programming, 1972
A family of real functions, calledr-convex functions, which represents a generalization of the notion of convexity is introduced. This family properly includes the family of convex functions and is included in the family of quasiconvex functions.

Let (x) be a convex downwards function, A > 0 a selfadjoint operator in a Hilbert space H, P an orthogonal projector in H; suppose DA PH is dense in PH, and let Ap be the Friedrichs extension of the operator PAP defined on DA PH. The inequality tr (Ap) ≤ tr (PAP) is proved. An estimate for the Jacobi θ-function and a distant generalization of the Szasz
