The algebra of smooth functions of rapid descent
Oleche, Paul O.; Ongati, Naftali O.; Agure, John O. (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
Stern, David; Ongati, Naftali O.; Agure, John O.; Ogange, Betty (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
Ongati, Naftali O.; Oleche, Paul O.; Agure, John O. (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) ...
