yes

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

Daoyuan CHEN

oh
Daoyuan CHEN

I see

make sense
Ho CHAN
01:11:12
So a basis of W is given by{ T^(-1)(x1),T^(-1)(x2),….T^(-1)(xn)}?
Ho CHAN
01:11:29
ok

I?
Zhiyi XING

identity matrix?

Daoyuan CHEN
01:27:55
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?
Daoyuan CHEN
01:29:37
oh
Daoyuan CHEN
01:29:43
ok
Ho CHAN
01:36:50
yes

Daoyuan CHEN

is there any difference between homeomorphic and isomorphic
Ho CHAN
01:50:10
I think homeomorphic is a topological concept?
Daoyuan CHEN
01:50:45
ok
Daoyuan CHEN
01:51:05
But I am thinking is there some example such that it is one but not one another
Daoyuan CHEN
01:52:02
ok
