Title of Talk
Stochastic control problems for markets with finite liquidity: Optimal trading strategies, super-hedging and modeling of transient price impact.

Abstract for Talk

In these lectures, I gave a survey of recent results for stochastic optimal control in models of financial markets where liquidity is finite, so that trading has a multiplicative and transient impact on prices. This is in contrast to the classical friction-less classical Black-Scholes theory in mathematical finance, which assumes liquidity to be unlimited or traders being small (i.e. having no price impact). We discussed transient inter-temporal price impact, optimal liquidation and super-hedging strategies, stochastic liquidity and modeling questions. My presentations were based on papers with Todor Bilarev and Peter Frentrup, preprints available on arXiv.
