Bipartite minors

Journal of Combinatorial Theory, Series B, 2016
We introduce a notion of bipartite minors and prove a bipartite analog of Wagner's theorem: a bipartite graph is planar if and only if it does not contain $K_{3,3}$ as a bipartite minor. Similarly, we provide a forbidden minor characterization for outerplanar graphs and forests.

Toeplitz Minors

Journal of Combinatorial Theory, Series A, 2002
Let \(T_{n-1} (f)\) denote the \(n\times n\) Toeplitz matrix generated by the Fourier coefficients of the function \(f\) on the unit circle \(\mathbf{T}\) and let \(D_{n-1} (f)=\det T_{n-1} (f)\). The well known strong Szegö limit theorem asserts that if \(\sigma (t)=\exp \left(\sum_{n=-\infty}^\infty c_nt^n\right)\) then \(D_{n-1}(\sigma)\sim \exp ...
