Asymptotic expansions of Green functions and spectral densities associated with partial differential operators are widely applied in quantum field theory and elsewhere. The mathematical properties of these expansions can be clarified and more precisely determined by means of tools from distribution theory and summability theory. (These are the same, insofar as recently the classic Cesàro–Riesz ...

We define the notion of rational payoffs in stochastic games. We then prove that the set of rational payoffs coincides with the set of extensive form correlated equilibrium payoffs; those are equilibrium payoffs in an extended game that includes an autonomous correlation device: a device that sends at every stage a private signal to each player, which is independent of the play, but may depend ...

This paper investigates the ability of the largest producer in an electricity market to manipulate both the electricity and emission allowances markets to its advantage. A Stackelberg game to analyze this situation is constructed in which the largest firm plays the role of the leader, while the medium-sized firms are treated as Cournot followers with price-taking fringes that behave competitive...

As a result of the pressing challenges in the Nigerian power sector and the looming effects of global climate change, the need arises for engineers to design and implement reliable renewable energy systems to mitigate the duo. This paper proffers the Green Village Electricity Project as a suitable model for providing offgrid solar electricity to remote settlements in Nigeria while dousing the e...

The recent strong increase in the penetration of renewable energy sources (RESs) medium-voltage distribution grids (MVDNs) has raised need for congestion management such grids, as they were not designed this new condition. This paper examines to what extent producing green hydrogen through electrolyzers can profitably contribute alleviation MVDNs presence high amounts RES, well flexible consume...

Albert Einstein discovered the theoretical foundations on which photovoltaic cells are based a hundred years ago — it was a spin-off from his annus mirabilis. Half a century ago, Bell labs built solar cells out of silicon, which soon came to be used in space flight. But the real breakthrough in solar cells was neither theoretical, nor experimental. It was a simple pecuniary reward. Since the 19...
