Learn how convexity adjustments in bonds affect interest rates and prices using key formulas. Understand their importance in accurately predicting bond price changes.

Preferred stocks have a higher convexity than conventional bonds. Call options lead to a phenomenon called negative convexity. Negative convexity can actually allow you to profit from preferred stocks ...

Programming theory is treated initially without any assumptions about the functions and with interpretation for production and activity analysis. By proof of a general theorem about optimal and ...

We study the convexity of integral means of subharmonic functions and the convexity of the variations of harmonic functions over certain level curves of some other harmonic functions in the plane.
