Question

Transcribed Image Text:Suppose
V
is a 4-dimensional vector space, and that
T
is a linear operator on
V
with minimal polynomial
x².
What can we say about the dimension of
ker T?

Transcribed Image Text:We must have
dim ker T =
2.
O We may have
dim ker T = 2
or
dim ker T
3.
O In general,
2 < dim ker T < 4
may hold.
