Analytic solutions and complete markets for the Heston model with stochastic volatility

Publikováno v: Electronic Journal of Differential Equations, Vol 2018, Iss 168,, Pp 1-54 (2018)

We study the Heston model for pricing European options on stocks with stochastic volatility. This is a Black-Scholes-type equation whose spatial domain for the logarithmic stock price $x\in \mathbb{R}$ and the variance $v\in (0,\infty)$ is the h

Positivity and negativity of solutions to nXn weighted systems involving the Laplace operator on R^N

Autor: Benedicte Alziary, Jacqueline Fleckinger, Marie-Helene Lecureux, Na Wei

Publikováno v: Electronic Journal of Differential Equations, Vol 2012, Iss 101,, Pp 1-14 (2012)

We consider the sign of the solutions of a $n imes n$ system defined on the whole space $mathbb{R}^N$, $Ngeq 3$ and a weight function $ho$ with a positive part decreasing fast enough, $$ -Delta U = lambda ho(x) MU +F, $$ where $F$ is a vector of func

Compactness for a Schrodinger operator in the ground-state space over $mathbb{R}^N$

Autor: Benedicte Alziary, Peter Takac

Publikováno v: Electronic Journal of Differential Equations, Vol Conference, Iss 16, Pp 35-58 (2007)

We investigate the compactness of the resolvent $(mathcal{A} - lambda I)^{-1}$ of the Schrodinger operator $mathcal{A} = - Delta + q(x)ullet$ acting on the Banach space $X$,$$ X = { fin L^2(mathbb{R}^N): f / varphiin L^infty(mathbb{R}^N) } ,quad | f|

Variational methods for a resonant problem with the p-Laplacian in $R^N$

Autor: Benedicte Alziary, Jacqueline Fleckinger, Peter Takac

Publikováno v: Electronic Journal of Differential Equations, Vol 2004, Iss 76, Pp 1-32 (2004)

The solvability of the resonant Cauchy problem $$ - Delta_p u = lambda_1 m(|x|) |u|^{p-2} u + f(x) quadhbox{in } mathbb{R}^N ;quad uin D^{1,p}(mathbb{R}^N), $$ in the entire Euclidean space $mathbb{R}^N$ ($Ngeq 1$) is investigated as a part of the Fr
