The first order partial differential equations resolved with any derivatives [PDF]

open access: yesarXiv, 2017
In this paper we discuss the first order partial differential equations resolved with any derivatives. At first, we transform the first order partial differential equation resolved with respect to a time derivative into a system of linear equations.

Partial correlation graphs for continuous-parameter time series [PDF]

open access: yesarXiv
In this paper, we establish the partial correlation graph for multivariate continuous-time stochastic processes, assuming only that the underlying process is stationary and mean-square continuous with expectation zero and spectral density function. In the partial correlation graph, the vertices are the components of the process and the undirected edges
