Quadratic Variation and Semimartingales
Probability and Its Applications, 2015We now come to one of the key objects in stochastic analysis, and what fundamentally distinguishes the theory from classical calculus. This is the notion of the quadratic variation of a process.

Decomposition of Quadratic Variational Problems
2008Variational problems have proved of value in many image processing and analysis applications. However increase of sensor resolution as occurred in medical imaging and experimental fluid dynamics demand for adapted solving strategies to handle the huge amount of data.

For the remainder of this book, we shall only consider integrators M which are continuous local martingales. By Proposition 1.9 these are automatically local L 2-martingales. A more extensive treatment, encompassing right continuous integrators would require more elaborate considerations which are not suitable for inclusion in this short book.

Quadratic variation of deformations
1997Hitherto no constitutive formalism of deformations provides a parameterization for the visually obvious features of their transformation grids. This paper notes a property of the thin-plate spline that one may exploit to this end. The bending energy that is minimized by the spline, usually expressed in matrix form, is also the double integral of the ...

OPERATOR PROCESSES MAJORIZING THEIR QUADRATIC VARIATION
Infinite Dimensional Analysis, Quantum Probability and Related Topics, 2000We give a full classification of convolution semigroups of completely positive mappings on Hopf algebras. Using the theory of noncommutative Lévy processes, we prove that these convolution semigroups are solutions of Hudson–Parthasarathy quantum stochastic differential equations. The generating process satisfies a positivity condition on the kernel of
