Uniformly Continuous Generalized Sliding Mode Control

Mathematics
This paper explores a general class of singular kernels with the objective of designing new families of uniformly continuous sliding mode controllers. The proposed controller results from filtering a discontinuous switching function by means of a Sonine ...

Operator function associated with an order preserving operator inequality [PDF]

Journal of Mathematical Inequalities, 2009
A capital letter means a bounded linear operator on a Hilbert space H. The celebrated Lowner-Heinz inequality asserts that A B 0 ensures A α B α for any α ∈ (0,1) ,b utA p B p does not always hold for p > 1.

An Extension to the Owa-Srivastava Fractional Operator with Applications to Parabolic Starlike and Uniformly Convex Functions

International Journal of Differential Equations, 2009
Let 𝒜 be the class of analytic functions in the open unit disk . We define Θα,β:𝒜→𝒜 by (Θα,βf)(z):=Γ(2−α)zαDzα(Γ(2−β)zβDzβf(z)),(α,β≠2,3,4…), where Dzγf is the fractional derivative of f of order γ. If α,β∈[0,1], then a function f

Classification of Hyperspectral Images Based on Supervised Sparse Embedded Preserving Projection

Applied Sciences, 2019
Dimensionality reduction is an important research area for hyperspectral remote sensing images due to the redundancy of spectral information. Sparsity preserving projection (SPP) is a dimensionality reduction (DR) algorithm based on the l1-graph, which ...

Part 1 of Martin’s Conjecture for order-preserving and measure-preserving functions

Journal of the American Mathematical Society
Martin’s Conjecture is a proposed classification of the definable functions on the Turing degrees. It is usually divided into two parts, the first of which classifies functions which are not above the identity and the second of which classifies functions which are above the identity.
