Conservative inclusion of Nörlund methods
P. L. Robinson
We offer practical necessary and sufficient conditions in order that every sequence convergent relative to the Nörlund summation method be convergent relative to the Nörlu…
Marcel Riesz on Nörlund Means
P. L. Robinson
We note that the necessary and sufficient conditions established by Marcel Riesz for the inclusion of regular Nörlund summation methods are in fact applicable quite generally.
Finite Nörlund Summation Methods
P. L. Robinson
We draw attention to simplifications in the theory of a Nörlund summation method that arise when the series is convergent.
completeness for Fourier series
P. L. Robinson
We note that the Fubini theorem may be used to prove that an function is determined by its Fourier coefficients.
Berezin expectation and Clifford trace
P. L. Robinson
We show that in finite dimensions, the Berezin expectation on an exterior algebra corresponds to the trace on a Clifford algebra, the correspondence being mediated by what is effec…
The Clifford algebra and its antidual
P. L. Robinson
We analyze the purely algebraic antidual of the complex Clifford algebra over a real inner product space . In particular, we introduce a partially defined product…
Partial Inner Products on Antiduals
P. L. Robinson
We discuss extensions of an inner product from a vector space to its full antidual. None of these extensions is weakly continuous, but partial extensions recapture some familiar st…
Self-dual Harmonicity: the planar case
P. L. Robinson
We present a manifestly geometrically self-dual version of the Fano harmonicity axiom for the projective plane.
