WebApr 11, 2024 · Assuming additionally that the coefficients μ, σ lead to affine Volterra processes, weak uniqueness was obtained in [1], [3], [12], [20]. However, as we do not impose a convolution structure on the stochastic Volterra equation (1.1), we cannot rely on the known results regarding the existence of weak solutions. WebThe existence of strong solutions and pathwise uniqueness are established for one-dimensional stochastic Volterra equations with locally H{\\"o}lder continuous diffusion coefficients and sufficiently regular kernels.
