Dirac delta function by Ciro Santilli 37 Updated +Created
The "0-width" pulse distribution that integrates to a step.
There's not way to describe it as a classical function, making it the most important example of a distribution.
Applications:

Chain rule by Ciro Santilli 37 Updated +Created
Here's an example of the chain rule. Suppose we want to calculate:
So we have:
and so:
Therefore the final result is:
Total derivative by Ciro Santilli 37 Updated +Created
The total derivative of a function assigns for every point of the domain a linear map with same domain, which is the best linear approximation to the function value around this point, i.e. the tangent plane.
E.g. in 1D:
and in 2D:

Holomorphic function by Ciro Santilli 37 Updated +Created
Being a complex holomorphic function is an extremely strong condition.
The existence of the first derivative implies the existence of all derivatives.
Another extremely strong consequence is the identity theorem.
"Holos" means "entire" in Greek, so maybe this is a reference to the fact that due to the identity theorem, knowing the function on a small open ball implies knowing the function everywhere.

Ciro Santilli's selfish desires by Ciro Santilli 37 Updated +Created
Just enough money to raise 3 kids in a rich country without having to work (so he can focus on whatever project he wants) and no more. Then maximize fame.
Fame is slightly convertible into money with generally little liquidity, but is more valuable if money becomes useless in a TEOTWAWKI.
Of course, in the end, one just does whatever seems cool and useful, and the Gods decide what proportion of fame/money/power they will get. Due to Ciro's love of open source software however, a higher fame percentage seems more likely than money.
Searching just for just "Santilli" on Google does not give any Ciro Santilli hits. The name appears to be a minor variation of the much more common "Santini". Since the name is not that common, it is possible to go over all noteworthy hits. Some relevant ones are shown at: interesting members of the Santilli family.
Searching just for just "Ciro" on Google does not give any Ciro Santilli hits, mostly some smaller brands that could be beaten, this is Ciro's main initial fame metric goal. Reaching it would require doing things known much beyond the programming community however, as Ciro has done until of 2019. ciro.com is from an electromechanics consultancy as of 2019, so it's not bad, let them be.
At the next useless gamified level, an honorary OBE and more ambitiously ForMemRS from the Royal Society post nominal letters would be nice.
The ultimate dream however would be to beat Cyrus the Great himself on Google searches ("Ciro" == "Cyrus" in Portuguese), maybe becoming "Cyrus the Greater"? That one will be a bit harder though. Maybe if Falung Gong becomes the dominant religion in 2000 years like Christianism did, catapulting the Judaism benefactor Cyrus into greater fame, then there is some hope for Ciro as well.
