H-principle for corank two distributions of odd rank and maximal first Kronecker index

Milan Jovanovic, Igor Zelenko

We study corank-two distributions $D$ of odd rank $2 N + 1$ whose associated pencil of skew-symmetric forms ${d α ∣_{D} (q) ∣ α \in Ω^{1} (M), α ∣_{D} = 0}$ lies, at every point, in the gen…

Morse inequalities for ordered eigenvalues of generic self-adjoint families

Gregory Berkolaiko, Igor Zelenko

In many applied problems one seeks to identify and count the critical points of a particular eigenvalue of a smooth parametric family of self-adjoint matrices, with the parameter s…
