On some properties of the superposition operator on topological manifolds [PDF]

open access: yesOpuscula Mathematica, 2010
In this paper the superposition operator in the space of vector-valued, bounded and continuous functions on a topological manifold is considered. The acting conditions and criteria of continuity and compactness are established.

Continuity of the superposition operator on Orlicz-Sobolev spaces [PDF]

open access: yesBulletin of the Australian Mathematical Society, 1994
We give sufficient conditions for a homogeneous superposition operator to be a continuous mapping between Orlicz-Sobolev spaces. This extends a result of Marcus and Mizel concerning mappings between Sobolev spaces.

Uniformly Continuous Superposition Operators In The Space Of Functions Of Bounded n-Dimensional Φ-Variation

open access: yesDemonstratio Mathematica, 2014
We prove that if a superposition operator maps a subset of the space of all metric-vector-space-valued-functions of bounded n-dimensional Φ-variation into another such space, and is uniformly continuous, then the generating function of the operator is an

Quantum conformal symmetries for spacetimes in superposition [PDF]

open access: yesQuantum, 2022
Without a complete theory of quantum gravity, the question of how quantum fields and quantum particles behave in a superposition of spacetimes seems beyond the reach of theoretical and experimental investigations.

Modelling of superposition in 2D linear acoustic wave problems using Fourier neural operator networks [PDF]

open access: yesActa Acustica
A method of solving the 2D acoustic wave equation using Fourier Neural Operator (FNO) networks is presented. Various scenarios including wave superposition are considered, including the modelling of multiple simultaneous sound sources, reflections from ...

Limits of Inner Superposition Operators and Young Measures

open access: yesZeitschrift für Analysis und ihre Anwendungen, 1999
We apply some well known theorems from the theory of Young measures to the theory of inner superposition (composition) operators. We give an explicit characterization of the limit operator of a weak-convergent sequence of inner superposition operators between Lebesgue spaces.

CONTINUITY OF SUPERPOSITION OPERATORS ON DOUBLE SEQUENCES SPACES OF MADDOX C_{r0} (p)

open access: yesRomanian Journal of Mathematics and Computer Science, 2015
Sagır and Gungor defined the superposition operator P_g where g:N^2 × R → R by P_g ((x_{ks})) = g (k, s, x_{ks}) for all real double sequences (x_{ks}). Chew &Lee and Petranuarat & Kemprasit characterized P_g : c_0 → l_1 and _Pg : c_0 → l_q where 1 ≤ q

Weighted superposition operators on Fock spaces [PDF]

open access: yes, 2022
We characterize all pairs of entire functions (u,ψ) for which the induced weighted superposition operator S(u,ψ) transforms one Fock space into another Fock space.

On solutions of some delay Volterra integral problems on a half-line

open access: yesNonlinear Analysis, 2021
In this paper, we study the existence of a.e. monotonic solutions of some general delay integral problems for both fractional and integer orders in the space of Lebesgue integrable functions on the interval R+ = [0;1) and in the space of locally ...
