Construction of efficient general linear methods for non-stiff differential systems
Mathematical Modelling and Analysis, 2012 This paper describes the construction of explicit general linear methods in Nordsieck form with inherent quadratic stability and large areas of the stability region.

Conditions for mutation-order speciation [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2010 Two models for speciation via selection have been proposed. In the well-known model of ‘ecological speciation’, divergent natural selection between environments drives the evolution of reproductive isolation. In a second ‘mutation-order’ model, different, incompatible mutations (alleles) fix in different populations adapting to the same selective ...

Conditions for the Oscillation of Solutions to Neutral Differential Equations of Higher Order
Mathematics, 2023 In this research, we applied three techniques—the comparison technique, the Riccati technique, and the integral averages technique to analyze and establish various conditions and properties associated with the oscillatory behavior of even-order neutral ...

Conditional expectation without order [PDF]
Pacific Journal of Mathematics, 1984 The authors show that an arbitrary contractive projection on a \(J^*\)- algebra has the properties of a conditional expectation. This is then used to solve the bicontractive projection problem for \(J^*\)-algebra. A \(J^*\)-algebra is a norm closed subspace of \({\mathcal L}(H,K)\) which is stable under the triple product \(\{abc\}=1/2(ab^*c+cb^*a ...

Conditional Expectation and Ordering [PDF]
The Annals of Probability, 1979 Let $(\Omega, \mathscr{A}, \mu)$ be a probability space and let $L$ be an ideal in $M(\Omega, \mathscr{A}, \mu)$ containing $\chi_\Omega$. A one-one correspondence between the class of "order closed" linear subspaces of $L$ and the sub $\sigma$-algebras of $\mathscr{A}$ is proved.

Nordsieck methods with inherent quadratic stability
Mathematical Modelling and Analysis, 2011 We derive suffcient conditions which guarantee that the stability polynomial of Nordsieck method for ordinary differential equations has only two nonzero roots. Examples of such methods up to order four are presented which are A-and L-stable.

An Engel condition for orderable groups [PDF]
Bulletin of the Brazilian Mathematical Society, New Series, 2015 Let m,n be positive integers, v a multilinear commutator word and w=v^m. We prove that if G is an orderable group in which all w-values are n-Engel, then the verbal subgroup v(G) is locally nilpotent. We also show that in the particular case where v=x the group G is nilpotent (rather than merely locally nilpotent).

On a Conjecture in Second-Order Optimality Conditions [PDF]
Journal of Optimization Theory and Applications, 2018 In this paper we deal with optimality conditions that can be verified by a nonlinear optimization algorithm, where only a single Lagrange multiplier is avaliable. In particular, we deal with a conjecture formulated in [R. Andreani, J.M. Martinez, M.L.

Second-order optimality conditions for interval-valued functions
Journal of Inequalities and Applications, 2023 This work is included in the search of optimality conditions for solutions to the scalar interval optimization problem, both constrained and unconstrained, by means of second-order optimality conditions.
