It is shown that, for a class of unital C\*-algebras including purely infinite simple C\*-algebras, real rank zero simple AT algebras, and AF algebras, if u and v are almost commuting unitaries where u has trivial K 1 -class, v has full spectrum, and a certain K 0 -valued obstruction associated to t
Each square complex matrix is unitarily similar to an upper triangular matrix with diagonal entries in any prescribed order. Let A = [a ij ] and B = [b ij ] be upper triangular n × n matrices that • are not similar to direct sums of square matrices of smaller sizes, or • are in general position an
Let be a finite set of nonzero linear forms in several variables with coefficients in a field K of characteristic zero. Consider the K-algebra C of rational functions generated by 1/α α ∈ . Then the ring ∂ V of differential operators with constant coefficients naturally acts on C . We study the gr
