Isolophile 

Isolophilia is referred to as having a strong affection and preference for solitude, and to be alone. This is not necessarily a negative term either, or something that has negative effects. For some isolophiles, this can be as simple as preferring their own company, and going out by themselves to eat or go for coffee. Or perhaps just feeling much more comfortable by themselves.

She would prefer to stay home because she’s an isolophile; she enjoys her isolophilia.

Isolating Yourself 

When you hide in corners, keep to yourself excessively, like to be alone and are slightly scared of people.

Doctor: Anya, stop isolating yourself. You're going to become a hermit.

Anya: OK. (Makes a weird noise and runs out of the room, slamming the door behind her and locking herself into the bathroom)

Isolic 

When a form of media makes you feel some sort of autophobia, triggered by an extreme fear of loneliness possibly due to the presence of a very few characters in that movie or show and also the type of world it was set in.

This term can also be used to describe the genre of that media.

Raja - Hey, did you watch that movie "Cast Away" by Tom Hanks?

Alex - Yes I did and it made me feel so isolic.

That game Ecco the Dolphin is so isolic, I felt really lonely while playing it.

isomorphism

Abstract algebra: Take a group G, and a group H, with a group operation *. G is isomorphic to H if there exist a map f: G->H such that:

1: f is injective
2: f is surjective
3: f(a*b)=f(a)*f(b) for all a,b in G

If f satisfies these three properties, f is called an isomorphism.

The map f: Z -> E given by f(a)=2a where Z is the integers and E is the even integers is an isomorphism.

Proof:
Showing injectivity

f(b)=f(a) => 2a=2b (from the given function) <=> a=b

Showing surjectivity
Suppose n is in E. n is an even integer hence n=2k for some integer k.

f(k)=2k=n, hence f is surjective.

Homomorphism:
f(a+b)=2(a+b)=2a+2b=f(a)+f(b)

Hence f is an isomorphism. Q. E. D.
