Derivation of an upper bound of the constant in the error bound for a near best m-term approximation Wissenschaftlicher BeitragIn the paper "The best m-term approximation and greedy algorithms" (V. N. Temlyakov), an error bound for a near best m-term approximation of a function g in L^p([0,1]^d) is provided, using a basis L^p-equivalent to the ...
Infinite divisibility of random fields admitting an integral representation with an infinitely divisible integrator Wissenschaftlicher BeitragWe consider random fields that can be represented as integrals of deterministic functions with respect to infinitely divisible random measures and show that these random fields are infinitely divisible.
Wissenschaftlicher BeitragTwo methods to approximate infinitely divisible random fields are presented. The methods are based on approximating the kernel function in the spectral representation of such fields, leading to numerical integration of the ...
