Uncertainty Estimates in the Heston Model via Fisher Information

Oliver Pfante, Nils Bertschinger

We address the information content of European option prices about volatility in terms of the Fisher information matrix. We assume that observed option prices are centred on the th…

Volatility Inference and Return Dependencies in Stochastic Volatility Models

Oliver Pfante, Nils Bertschinger

Stochastic volatility models describe stock returns as driven by an unobserved process capturing the random dynamics of volatility . The present paper quantifies how muc…

Inferring Volatility in the Heston Model and its Relatives -- an Information Theoretical Approach

Nils Bertschinger, Oliver Pfante

Stochastic volatility models describe asset prices as driven by an unobserved process capturing the random dynamics of volatility . Here, we quantify how much informatio…

Chern-Simons theory for the noncommutative 3-torus

Oliver Pfante

We study the Chern-Simons action, which was defined for noncommutative spaces in general by the author, for the noncommutative 3-torus, the universal C*-algebra generated by 3 unit…

A Chern-Simons action for noncommutative spaces in general with the example SU_q(2)

Oliver Pfante

Witten constructed a topological quantum field theory with the Chern-Simons action as Lagrangian. We define a Chern-Simons action for 3-dimensional spectral triples. We prove gauge…

Equivariant K-theory of finite dimensional real vector spaces

Siegfried Echterhoff, Oliver Pfante

We give a general formula for the equivariant complex -theory of a finite dimensional real linear space equipped with a linear action of a compact group in te…
