I want to say that a given topic e.g. ODE permeates all of mathematics..

Ubiquity

? , or , ?

? , or , ?

I will show you a famous place where the comma is there, but the "?" seems to be missing and then show where it should possibly be, plus a more elegant alternative.

"To be, or not to be, that is the question:
Whether 'tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles
And by opposing end them. To die—to sleep,
No more; and by a sleep to say we end
The heart-ache and the thousand natural shocks
That flesh is heir to: 'tis a consummation
Devoutly to be wish'd. To die, to sleep;
To sleep, perchance to dream—ay, there's the rub:
For in that sleep of death what dreams may come,
When we have shuffled off this mortal coil,
Must give us pause—there's the respect
That makes calamity of so long life..."

a) To be, or not to be?, that is the question:

or, better a long dash (visual improvement and yet does not lose the intended pause)

b) To be, or not to be? – that is the question:

Do be do be do

- Sinatra

"To be is to do."
- Socrates

"To do is to be."
- Jean-Paul Sartre

Where did that triumvirate appear?

Do not Google it!

A hint: KV
Ecrivain

Sorry small iPhone keyboard typo corrected - not ecrivan

I am being a little elliptical there not to give it away too easily

Ecrivain = writer
KV = writers initials

You can google now if you want

I don’t mean to torture anyone... : D

Enough problems in the world already!

Escrivain, escriva in Barcelona, escribano in Madrid... KV = Kurt Vonnegut?
No idea what you're talking about!

Very good guess.  

The quote of the three phrases, from Socrates to Sartre to Sinatra, comes from Vonnegut's novel Deadeye Dick, where it is seen as a piece of graffiti somewhere. (1982).

The real story goes further than that, but it is a fun set of beings and doings to which you can also add Lao Tzu, Albert Camus, and various other philosophers.
