‎in this paper‎, ‎a spectral tau method for solving fractional riccati‎ ‎differential equations is considered‎. ‎this technique describes‎ ‎converting of a given fractional riccati differential equation to a‎ ‎system of nonlinear algebraic equations by using some simple‎ ‎matrices‎. ‎we use fractional derivatives in the caputo form‎. ‎convergence analysis of the proposed method is given an...

global health 2035, the report of the lancet commission on investing in health, laid out a bold, highly ambitious framework for making rapid progress in improving global public health outcomes. it showed that with the right health investments, the international community could achieve a “grand convergence” in global health—a reduction in avertable infectious, maternal, and child deaths down to ...

Purpose: The main aim of this paper is to present a concept marginal vertical income convergence. This method allows determine the individual contribution objects (countries, regions) observed general process real Design/Methodology/Approach: Proposed methodology avoid limitations classical analysis To check cross-country stability parameters and assess an convergence process, separate regressi...
