WebDec 31, 2015 · A function has a left inverse just when it's one to one (injective) - it never takes the same value twice. A linear functions defined by a matrix never takes any value twice just when it never takes the value 0 twice. That's when the kernel is just { 0 }. You … WebFeb 7, 2011 · Therefore, a right inverse doesn't exist in this case. I said, we can speak about the existence of right and left inverse (i.e. it has sense to define them). Of course left and/or right inverse could not exist. Choosing for example \displaystyle a=b=0 a = b = 0 does not exist \displaystyle R R and does not exist \displaystyle L L. Fernando Revilla
WebBy above, we know that f has a left inverse and a right inverse. Therefore it has a two-sided inverse. This proof is invalid, because just because it has a left- and a right inverse does not imply that they are actually the same function. Valid Proof ( ⇒ ): Suppose f is bijective. By above, we know that f has a left inverse and a right inverse. Webleft A rectangular matrix can’t have a two sided inverse because either that matrix or its transpose has a nonzero nullspace.
