The pointwise completeness and the pointwise degeneracy of linear discrete-time different fractional order systems [PDF]

open access: goldBulletin of the Polish Academy of Sciences: Technical Sciences, 2020
Necessary and sufficient conditions for the pointwise completeness and the pointwise degeneracy of linear discrete-time different fractional order systems are established. It is shown that if the fractional system is pointwise complete in one step (q = 1)

Pointwise approximation by elementary complete contractions [PDF]

open access: bronzeProceedings of the American Mathematical Society, 2009
A complete contraction on a C*-algebra A, which preserves all closed two sided ideals J, can be approximated pointwise by elementary complete contractions if and only if the induced map on the tensor product of B with A/J is contractive for every C*-algebra B, ideal J in A and C*-tensor norm on the tensor product.

Compact and Interpretable Neural Networks Using Lehmer Activation Units [PDF]

open access: yesEntropy
We introduce Lehmer Activation Units (LAUs), a class of aggregation-based neural activations derived from the Lehmer transform that unify feature weighting and nonlinearity within a single differentiable operator.

Inductive Definition and Domain Theoretic Properties of Fully Abstract [PDF]

open access: yesLogical Methods in Computer Science, 2007
A construction of fully abstract typed models for PCF and PCF^+ (i.e., PCF + "parallel conditional function"), respectively, is presented. It is based on general notions of sequential computational strategies and wittingly consistent non-deterministic ...
