The equal effectiveness of different defensive strategies

Plants have evolved a variety of defensive strategies to resist herbivory, but at the interspecific level, the relative effectiveness of these strategies has been poorly evaluated. In this study, we compared the level of herbivory between species that depend on ants as indirect defenders and species that rely primarily on their own direct defenses. Using a dataset of 871 species and 1,405 data ...

Two algorithms for solving comrade linear systems

In this paper, we present an efficient computational and symbolic algorithms for solving comrade linear systems. The implementation of the algorithms using Computer Algebra Systems (CAS) such as MAPLE, MACSYMA, MATHEMATICA, and MATLAB is straightforward. An examples are given in order to illustrate the algorithms. 2006 Elsevier Inc. All rights reserved.

Fiedler-comrade and Fiedler-Chebyshev pencils

Fiedler pencils are a family of strong linearizations for polynomials expressed in the monomial basis, that include the classical Frobenius companion pencils as special cases. We generalize the definition of a Fiedler pencil from monomials to a larger class of orthogonal polynomial bases. In particular, we derive Fiedler-comrade pencils for two bases that are extremely important in practical ap...
