A dynamic matrix exponential via a matrix cylinder transformation

In this work, we develop a new matrix exponential on time scales via a cylinder transformation with a component-wise, locally mu(Delta)-integrable square matrix subscript. Our resulting matrix function can be written in terms of the matrix exponential of a Lebesgue integral added to a logarithmic sum in terms of the gaps of a general time scale. Under strict commutativity conditions, we show our dynamic matrix exponential is equivalent to the one in the standard literature. Finally, we demonstrate that our matrix exponential satisfies a nonlinear dynamic integral equation. (C) 2019 Elsevier Inc. All rights reserved.
