A survey on non-linear oscillations
Derek P. Atherton,H. T. Dorrah +1 more
TL;DR: A comprehensive review of work in the field of non-linear oscillations can be found in this paper, where a brief discussion of second-order systems is followed by a presentation of exact criteria, approximate analytical methods and computational techniques for limit cycles in single variable systems.

On some metrical properties of operator matrices and matrices partitioned into blocks
TL;DR: In this article, the Laplacian expansion by the elements of a row is no longer true in the general case of an arbitrary block-matrix, and the representa-a-n relation shows that we can make some computations with similarly partitioned matrices by treating the blocks as if they were individual elements of the matrix.

Estimates for the inverse of a matrix
TL;DR: In this paper, the problem of finding bounds for the elements of the inverse of a matrix satisfying various known regularity conditions is considered, and the results are obtained in such a way as to apply automatically to partitioned matrices.
