Quantum Field Theory of Forward Rates with Stochastic Volatility [PDF]

open access: yes, 2001
In a recent formulation of a quantum field theory of forward rates, the volatility of the forward rates was taken to be deterministic. The field theory of the forward rates is generalized to the case of stochastic volatility. Two cases are analyzed, firstly when volatility is taken to be a function of the forward rates, and secondly when volatility is ...

The Heston stochastic volatility model in Hilbert space [PDF]

open access: yesarXiv, 2017
We extend the Heston stochastic volatility model to a Hilbert space framework. The tensor Heston stochastic variance process is defined as a tensor product of a Hilbert-valued Ornstein-Uhlenbeck process with itself. The volatility process is then defined by a Cholesky decomposition of the variance process.

Stock Price Dynamics and Option Valuations under Volatility Feedback Effect [PDF]

open access: yes, 2012
According to the volatility feedback effect, an unexpected increase in squared volatility leads to an immediate decline in the price-dividend ratio. In this paper, we consider the properties of stock price dynamics and option valuations under the volatility feedback effect by modeling the joint dynamics of stock price, dividends, and volatility in ...

An Hilbert space approach for a class of arbitrage free implied volatilities models [PDF]

open access: yesarXiv, 2007
We present an Hilbert space formulation for a set of implied volatility models introduced in \cite{BraceGoldys01} in which the authors studied conditions for a family of European call options, varying the maturing time and the strike price $T$ an $K$, to be arbitrage free. The arbitrage free conditions give a system of stochastic PDEs for the evolution

Analysing Quantiles in Models of Forward Term Rates

open access: yesRisks, 2023
The class of forward-LIBOR market models can, under certain volatility structures, produce unrealistically high long-dated forward rates, particularly for maturities and tenors beyond the liquid market calibration instruments.

Adaptive neural network surrogate model for solving the implied volatility of time-dependent American option via Bayesian inference

open access: yesElectronic Research Archive, 2022
In this paper, we propose an adaptive neural network surrogate method to solve the implied volatility of American put options, respectively. For the forward problem, we give the linear complementarity problem of the American put option, which can be ...
