A function $f$ is like an infinite dimensional vector with the norm $|f| = \int^b_a f(t)^2 \, \mathrm{d} t $ and dot product $f \cdot g = \int^b_a f(t) g(t) \, \mathrm{d} t $ where appropriate boundaries have to be chosen or you have to restrict functions so that problems with infinities don't p...
Given the following rather nice diagonal metric, the above is what happens when you try to write even one component of the 2nd order partial derivative of it in full
Well, if it appeared inside as one of the components, then it is the kronecker delta, but yeah I should have use other greek letters to minimsie confusion
Another question (sorry lol)... If the Kronecker delta is $\delta_{ij}$ and say $(i,j = 1,2...n)$ then is the Kronecker delta an identity matrix of dimensions nxn?
@0celóñe7 I've read a couple of things by a couple of people that reckon as they're running out of main characters due to, well, killing them off, they have to tone down the killing a bit for a season so that there are actually people alive when it gets to the final season...
@0celóñe7 The way that characters like that usually work out is that they stop caring enough about themselves and so, end up sacrificing themselves 'for the greater good', so it's quite possible
@Mithrandir24601 Hmm, yes. If we want to talk about main characters dying we'd have to list them. For instance, Varyss is basically the core of the plot for 5 seasons but the show isn't about him. Is he a main char?
@0celóñe7 I'd say he is, because if he dies, there's no-one to replace him that can do what he can do
@0celóñe7 Probably not any more, because if he died, Sansa would probably get his land etc. by right and she now knows how he works, as well as the people of the Vale, so again, there's someone to replace him who can also do what he does (unless there's something he knows that no-one else does, which is possible, although getting less and less likely)
@Mithrandir24601 Agreed, Baelish has become less and less important as the show goes on.
I'm not sure what his goal is right now except to marry Sansa (creepy) and get the Iron Throne (not sure how he thinks anyone will support that).
Cersei has proven that ruling through fear isn't going to work in the long-run and he doesn't have the armies to beat Dany. No clue what his plan is, or if it even matters anymore.
Oh. Ohhhh :o I think Cersei's no longer the one in control/power. Her 'Meister' is the one that's keeping her there, so he's the one that has the real power...
@0celóñe7 He's the only one that's actually done anything to keep Cersei in power (including Cersei herself). He's the one that got all the wildfire. He brought Clegane back as that creature, who seems to be the only guard that's truly loyal. However, he's probably loyal to Qyburn, not Cersei. So, Cersei is only ruling because of the Meister. What happens if he decides he wants power? he gets it instantly. So he's the one with the power
