A Note on Asplenium pinnatifidum Nuttall

A note on 'Efficient evaluation of polynomials and exponentials of polynomials for equispaced arguments' by A.H. Nuttall

Nutall's algorithm for the computation of PN(x) = E^o prx at xn = x0 + n\, n = 0, 1, 2, • • • requires converting PN(xn) to QN(n) ±?. N m = aann . Recursion is then carried out through Qk + , (n) = Qk + , (n 1) + gj(n), * = 0, 1, • • • , N 1. This requires the initial values fiv_r(0), r = 0, 1, 2, • • • , N. We present here explicit and easily programmable formulas for am as well as Q,v-r(0), i...

A note on vague graphs

In this paper, we introduce the notions of product vague graph, balanced product vague graph, irregularity and total irregularity of any irregular vague graphs and some results are presented. Also, density and balanced irregular vague graphs are discussed and some of their properties are established. Finally we give an application of vague digraphs.

A note on lifting projections

Suppose $pi:mathcal{A}rightarrow mathcal{B}$ is a surjective unital $ast$-homomorphism between C*-algebras $mathcal{A}$ and $mathcal{B}$, and $0leq aleq1$ with $ain  mathcal{A}$. We give a sufficient condition that ensures there is a proection $pin mathcal{A}$ such that $pi left( pright) =pi left( aright) $. An easy consequence is a result of [L. G. Brown and G. k. Pedersen, C*-algebras of real...

A Note on Finsler Modules

Asplenium merapohense (Aspleniaceae), a new species from the Peninsular Malaysia

A new species of Asplenium is described from two collections made on limestone hills in Peninsular Malaysia. Conspicuous by its extremely narrow pinnae, it is probably allied to A. salignum but differs in sufficient characters (scale size, size and shape of lamina, venation and sorus length, position and orientation) to be a species in its own right.
