---

Adding extra symmetries makes string theory problems easier to work

with and allows researchers to ask questions about the properties

of geometric structures and how they correspond to real-world physics.

---

Using their physics intuition, Lawrie and Lin were able to apply

their knowledge of math to make new discoveries that wouldn’t

have been possible if the two fields were used in isolation.

“What we found seems to suggest that theories in five dimensions

come from theories in six dimensions,” explains Lin.

“That is something that mathematicians, if they didn’t know

about string theory or physics, would not think about.”

Lawrie adds that being able to work directly with mathematicians

is also helpful in their field since understanding new math research

can be a challenge, even for theoretical physics researchers.

“As physicists, we can have a long discussion where we use a lot of intuition,

but if you talk to a mathematician they will say,

‘Wait, precisely what do you mean by that?’ and then you have to pull out

your important assumptions,” says Lawrie. “

It’s also good for clarifying our own thought process.”

My opinion

The mathematicians have no problem to create many - many

extra symmetries . . . but would '' they correspond to real-world physics'' ?

Adding extra symmetries mathematicians can make horse to fly like

the horse Pegasus because every new symmetry brings a new tiny change.
