Potentials of a Markov process are expected suprema

Hans Föllmer, Thomas Knispel (2007)

ESAIM: Probability and Statistics

Similarity:

Expected suprema of a function  observed along the paths of a nice Markov process define an excessive function, and in fact a potential if  vanishes at the boundary. Conversely, we show under mild regularity conditions that any potential admits a representation in terms of expected suprema. Moreover, we identify the maximal and the minimal representing function in terms of probabilistic potential theory. Our results are motivated by the work of El Karoui and Meziou (2006) on the max-plus...

Mean variance and goal achieving portfolio for discrete-time market with currently observable source of correlations

Nikolai Dokuchaev (2010)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

The paper studies optimal portfolio selection for discrete time market models in mean-variance and goal achieving setting. The optimal strategies are obtained for models with an observed process that causes serial correlations of price changes. The optimal strategies are found to be myopic for the goal-achieving problem and quasi-myopic for the mean variance portfolio.
