Decreasing and complete monotonicity of functions defined by derivatives of completely monotonic function involving trigamma function

Demonstratio Mathematica
In this study, using convolution theorem of the Laplace transforms, a monotonicity rule for the ratio of two Laplace transforms, Bernstein’s theorem for completely monotonic functions, and other analytic techniques, the authors verify decreasing property

The Bessel Wavelet Transform [PDF]

, 2011
In this paper continuity of the Bessel wavelet transform B ψ of function φ in terms of a mother wavelet ψ is investigated on certain distribution spaces when the Hankel transform of ψ defined by ψ(x, y) ∈ C ∞ (R 2 + ).

A surprising property of nonlocal operators: the deregularising effect of nonlocal elements in convolution differential equations

Advanced Nonlinear Studies
We consider nonlocal differential equations with convolution coefficients of the form−M(a*|u|q)(1)μ(t)u″(t)=λft,u(t), t∈(0,1), $$-M\left(\left(a {\ast} \vert u{\vert }^{q}\right)\left(1\right)\mu \left(t\right)\right){u}^{{\prime\prime}}\left(t\right ...

Explicit Solutions of Nonlocal Boundary Value Problems, Containing Bitsadze-Samarskii Constraints [PDF]

, 2010
MSC 2010: 44A35, 35L20, 35J05, 35J25In this paper are found explicit solutions of four nonlocal boundary value problems for Laplace, heat and wave equations, with Bitsadze-Samarskii constraints based on non-classical one-dimensional convolutions. In fact,

On the Uniform Convergence of Partial Dunkl Integrals in Besov-Dunkl Spaces [PDF]

, 2006
2000 Mathematics Subject Classification: 44A15, 44A35, 46E30In this paper we prove that the partial Dunkl integral ST(f) of f converges to f, as T → +∞ in L^∞(νµ) and we show that the Dunkl transform Fµ(f) of f is in L^1(νµ) when f belongs to a suitable ...

Connections between classical and generalised trajectories of a state/signal system [PDF]

, 2020
. In our earlier article "Well-posed state/signal systems in continuous time", we originally defined the notion of a trajectory of a state/signal system by means of a generating subspace.
