On D-stable and D-semistable matrices and the structured singular value

Proceedings of 35th IEEE Conference on Decision and Control, 2002
It is shown that testing a matrix A /spl isin/ R/sup nxn/ for discrete-time D-stability is equivalent to testing if the structured singular value (SSV or /spl mu/) of a matrix M /spl isin/ R/sup 2nx2n/ obtained from A, is less than unity. Testing for D-semistability (i.e.

The Capitalization, Amortization, and Value-relevance of R&D

Journal of Accounting and Economics, 1996
Abstract A direct relationship between research and development costs and specific future revenue generally has not been demonstrated, even with the benefit of hindsight. For example, three empirical research studies, which focus on companies in industries intensively involved in research and development activities, generally failed to ...

A model complete theory of valued D-fields

Journal of Symbolic Logic, 2000
AbstractThe notion of a D-ring, generalizing that of a differential or a differenee ring, is introduced, Quantifier elimination and a version of the Ax—Kochen—Eršov principle is proven for a theory of valued D-fields of residual characteristic zero.
