Conditional Path Decomposition at the Infimum and Maximum Drawdowns for Spectrally Negative Lévy Processes
Ceren Vardar Acar, Mine ÃaÄlar
We study maximum-drawdown laws conditioned on extremes for a spectrally negative Lévy process and observed up to an independent exponential time. The main contribution is a set of…

Chaotic and Predictable Representations for Markov Additive Processes with Levy Modulator
Celal Umut Yaran, Mine ÃaÄlar
Our main result is the martingale representations for Markov additive processes where the modulator is a Levy process. These processes have three parts: the modulator, the jumps of…

Long Time Behavior of General Markov Additive Processes
Celal Umut Yaran, Mine ÃaÄlar
We study general Markov additive processes when the state space of the modulator is a Polish space. Under some regularity assumptions, our main result is the characterization of th…
