A Generalisation of the Cauchy Integral Formula for Normal Matrices

Kippenhahn Varieties and the Weyl Calculus for Several Matrices I

“…Nelson's representation (32) suggests that the numerical range distribution ν A and the fundamental solution of F P A of P A (τ, D) = δ 0 must be related. The relationship is curiously the basis of the generalisation of the Cauchy integral formula considered in the paper [22] which intentionally does not mention the fundamental solution F P A .…”
