The algebra of smooth functions of rapid descent
(2009)
A bounded operator with the spectrum lying in a compact set V ⊂ R, has C∞ (V) functional calculus. On the other hand, an operator H acting on a Hilbert space H, admits a C(R) functional calculus if H is self-adjoint. So ...
Incremental modernization of statistics teaching and curriculum at Maseno University, Kenya
(ISI/IASE], 2010)
Modernisation of statistics teaching is a continual problem the world over. The advances in statistical methods and tools along with the growing demand of applied practitioners creates a dual need of people with the ...
Operators with slowly growing resolvents towards the spectrum
(Academic Publications, 1/13/2009)
A closed densely defined operator H, on a Banach space X, whose spectrum is contained in R and satisfies
(z −H)−1
≤ c hziα |=z|β ∀ z 6∈ R (0.1) for some α , β ≥ 0; c > 0, is said to be of (α, β)−type R . If instead of (0.1) ...
