University of Cambridge the Method of Iterated Commutators for Ordinary Diierential Equations on Lie Groups the Method of Iterated Commutators for Ordinary Diierential Equations on Lie Groups
We construct numerical methods to integrate ordinary diierential equations that evolve on Lie groups. These schemes are based on exponentials and iterated com-mutators, they are explicit and their order analysis is relatively simple. Thus we can construct group-invariant integrators of arbitrarily high order. Among other applications we show that this approach can be used to obtain new symplect...
متن کاملAn Upper Bound on the Global Optimum in Parameter Estimation
Learning graphical model parameters from incomplete data is a non-convex optimization problem. Iterative algorithms, such as Expectation Maximization (EM), can be used to get a local optimum solution. However, little is known about the quality of the learned local optimum, compared to the unknown global optimum. We exploit variables that are always observed in the dataset to get an upper bound ...
متن کاملImaginary Scators Bound Set Under the Iterated Quadratic Mapping in 1 + 2 Dimensional Parameter Space
The quadratic iteration is mapped within a non distributive imaginary scator algebra in 1+2 dimensions. The Mandelbrot set is identically reproduced at two perpendicular planes where only the scalar and one of the hypercomplex scator director components is present. However, the bound three dimensional S set projections change dramatically even for very small departures from zero of the second h...
متن کاملUpper Bound for Isometric Embeddings
The isometric embeddings 2;K → p;K (m ≥ 2, p ∈ 2N) over a field K ∈ {R,C,H} are considered, and an upper bound for the minimal n is proved. In the commutative case (K = H) the bound was obtained by Delbaen, Jarchow and Pe lczyński (1998) in a different way. Let K be one of three fields R,C,H (real, complex or quaternion). Let K be the K-linear space consisting of columns x = [ξi] n 1 , ξi ∈ K, ...
