On the Second Fundamental Theorem of Asset Pricing
Let be sigma-martingales on . We show
that every bounded martingale (with respect to the underlying filtration)
admits an integral representation w.r.t. if and only if there
is no equivalent probability measure (other than ) under which
are sigma-martingales.
From this we deduce the second fundamental theorem of asset pricing- that
completeness of a market is equivalent to uniqueness of Equivalent
Sigma-Martingale Measure (ESMM)
Size scale effect in cavitation erosion
An overview and data analyses pertaining to cavitation erosion size scale effects are presented. The exponents n in the power law relationship are found to vary from 1.7 to 4.9 for venturi and rotating disk devices supporting the values reported in the literature. Suggestions for future studies were made to arrive at further true scale effects
