1 homework 4, due wednesday, 5/4 in class, or in Vladimir’s box by 4:00pm 1. let V = { f ± ± f ( x,y ) is a polynomial of degree n with complex coefficients } and let T : V V be the operator ( Tf )( x,y ) = f ( y,x ) . a. show that every eigenvalue of T is 1 or - 1, using the fact that T 2 = Id . b. let U = Range ( T + 1), W = Range ( T - 1). if f V , show that Tf = - f + g, g U and Tf = f + h, h W if you’re stuck, think about the proof of the upper-triangular theorem.
