Existence Results for Tempered-Hilfer Fractional Differential Problems on Hölder Spaces
SymmetryThis paper considers a nonlinear fractional-order boundary value problem HDa,gα1,β,μx(t)+f(t,x(t),HDa,gα2,β,μx(t))=0, for t∈[a,b], α1∈(1,2], α2∈(0,1], β∈[0,1] with appropriate integral boundary conditions on the Hölder spaces.

Journal of Functional Analysis, 2019 We prove a sharp estimate for the k-modulus of smoothness, modelled upon a L p -Lebesgue space, of a function f in W k L p n n + k p , p ( Ω ) , where Ω is a domain with minimally smooth boundary and finite Lebesgue measure, k , n ∈ N , k n and n n − k p

A Fourier Analysis Based New Look at Integration
Annales Mathematicae Silesianae, 2023 We approach the problem of integration for rough integrands and integrators, typically representing trajectories of stochastic processes possessing only some Hölder regularity of possibly low order, in the framework of para-control calculus.

Coupling methods for random topological Markov chains
, 2014 We apply coupling techniques in order to prove that the transfer operators associated with random topological Markov chains and non-stationary shift spaces with the big images and preimages-property have a spectral gap.Comment: 17 ...

Small data scattering for a cubic Dirac equation with Hartree type nonlinearity in $ \R^{1+3}$ [PDF]
, 2019 We prove that the initial value problem for the Dirac equation $ \left ( -i\gamma^\mu \partial_\mu + m \right) \psi = \left(\frac{e^{- |x|}}{|x|} \ast ( \overline \psi \psi)\right) \psi \quad \text{in } \ \R^{1+3} $ is globally well-posed and the

International Journal of Mathematics and Mathematical Sciences, 2004 We present some resolvent estimates of elliptic differential and finite-element operators in pairs of function spaces, for which the first space in a pair is endowed with stronger norm. In this work we deal with estimates in (Lebesgue, Lebesgue), (Hölder,

Symmetry, 2018 This article concerns the entity of solutions of a quadratic integral equation of the Fredholm type with an altered argument, x ( t ) = p ( t ) + x ( t ) ∫ 0 1 k ( t , τ ) ( T x ) ( τ ) d τ , where p , k are given functions, T is the given operator ...

Weighted norm inequalities for the bilinear maximal operator on variable Lebesgue spaces [PDF]
, 2019 We extend the theory of weighted norm inequalities on variable Lebesgue spaces to the case of bilinear operators. We introduce a bilinear version of the variable $\A_\pp$ condition, and show that it is necessary and sufficient for the bilinear maximal ...

Induced topological pressure for countable state Markov shifts
, 2010 We introduce the notion of induced topological pressure for countable state Markov shifts with respect to a non-negative scaling function and an arbitrary subset of finite words.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
