Confluent Vandermonde matrices and divided differences over quaternions

Comptes Rendus. Mathématique, 2015
We introduce the notion of a confluent Vandermonde matrix over quaternions and present the formula to compute its rank. This extends a result of T.Y. Lam (A general theory of Vandermonde matrices, Expo. Math. 4 (3) (1986) 193–215). Another contribution is the representation formula for divided differences of quaternion polynomials which extends a ...

Electrophysiological function in eyes with reticular pseudodrusen according to fundus distribution. [PDF]

PLoS ONE, 2018
Reticular pseudodrusen (RPD) could be present not only in the posterior pole but extramacular area also as a confluent morphological pattern. Thus RPD can be classified by the fundus distribution for the assessment of visual prognosis.

Effect of aminomix-1 solution as an in vitro scolicidal agent on the bile ducts and liver in rats: a controlled experimental animal study [PDF]

São Paulo Medical Journal
BACKGROUND: Many scolicidal agents are used to treat hydatid cysts. However, most of these have been discontinued because of complications. Currently, no safe, effective, and useful scolicidal agent are available for the treatment of hydatid cysts in ...

Confluent Vandermonde matrices, divided differences, and Lagrange–Hermite interpolation over quaternions [PDF]

Communications in Algebra, 2016
We introduce the notion of a confluent Vandermonde matrix with quaternion entries and discuss its connection with Lagrange-Hermite interpolation over quaternions. Further results include the formula for the rank of a confluent Vandermonde matrix, the representation formula for divided differences of quaternion polynomials and their extensions to the ...
