Duality Theory in Filtering Problem for Discrete Volterra Equations
The ltering problem for discrete Volterra equations is a nontrivial task due to an increasing dimension of the equivalent single step process model A di erence equation of a moderate dimension is chosen as an approximate model for the original system Then the reduced Kalman lter can be used as an approximate but e cient estimator Using the duality theory of convex variational problems a level o...

متن کاملStability and Asymptoticity of Volterra Difference Equations: A Progress Report
We survey some of the fundamental results on the stability and asymptoticity of linear Volterra difference equations. The method of Z-transform is heavily utilized in equations of convolution type. An example is given to show that uniform asymptotic stability does not necessarily imply exponential stabilty. It is shown that the two notions are equivalent if the kernel decays exponentially. For ...
متن کاملStochastic Volterra integro-differential equations: stability and numerical methods
We consider the reliability of some numerical methods in preserving the stability properties of the linear stochastic functional differential equation ẋ(t) = αx(t) + β ∫ t 0 x(s)ds+ σx(t− τ )Ẇ (t), where α, β, σ, τ ≥ 0 are real constants, and W (t) is a standard Wiener process. We adopt the shorthand notation of ẋ(t) to represent the differential dx(t) etc. Our choice of test equation is a stoc...
