Fun question! I don’t know the answer other than to say it’s not just the algebraics because of the Gelfond-Schneider constant
Are you sure this is well-defined? You say that a and b are algebraic but “closure” implies that they could also be any members of S. This might mess up your proof that it’s not all the reals if you do mean the closure.
Currently, employees have the legal right to request flexible working, but there is no obligation on companies to agree. That balance of power is to be shifted, with companies instead legally obliged to offer flexible working from day one except where it is “not reasonably feasible”.
Seems this isn’t about a 4 day week specifically, but about employers being required to give their reasons when they reject flexible working requests. The telegraph is just using it as an example of something an employee could request.
Lapsang Souchong tea, most people seem to hate it. Also plastic glue
Use it to find the mooving average
All maths papers are like this
You could say something like “the image of exponentiation over…” to mean the set of values created by applying the function once, but it sounds slightly clunky.
Looks like there aren’t really very many sets of mostly transcendental numbers that have names. Computational numbers and periods are two of them, I’d guess that both probably contain your set, so you could compare with those to see where it gets you.
