yes

It seems T^-1*T=Iw and T*T^-1=Iv

ys

oh

I see

y

y

make sense

So a basis of W is given by{ T^(-1)(x1),T^(-1)(x2),….T^(-1)(xn)}?

ok

y

yes

I?

identity matrix?

ys

y

In previous proof, why do we need to two equations which are expanded by T*T^-1 and T^-1*T. I think only one is enough?

oh

ok

yes

y

is there any difference between homeomorphic and isomorphic

I think homeomorphic is a topological concept?

ok

But I am thinking is there some example such that it is one but not one another

ok

Thank you for attending the lecture.
