We will use K̂iφ as an abbreviation for ¬Ki¬φ and 〈φ〉ψ as an abbreviation for ¬[φ]¬ψ. Definition 2 (Semantics). An epistemic model (or model for short) is a triple M = (S,∼n, V ) with S a non-empty set of states, ∼i an equivalence relation for i < n, and V a function assigning a subset V (p) ⊆ S with each p ∈ PL. Given a modelM = (S,∼n, V ) and an s ∈ S, we define: M, s |= p iff s ∈ V (p) M, s |...
Given an oblique reflection map Γ and functions ψ, χ ∈ Dlim (the space of R -valued functions that have finite left and right limits at every point), the directional derivative ∇χΓ(ψ) of Γ along χ, evaluated at ψ, is defined to be the pointwise limit, as ε ↓ 0, of the family of functions ∇εχΓ(ψ) . = ε [Γ(ψ + εχ) − Γ(ψ)]. Directional derivatives are shown to exist and lie in Dlim for oblique ref...
It is pointed out that the judgment condition of time reversal symmetry in the processes of particle interaction is that the Hamiltioians of systems satisfy the relation Ĥ(t) = Ĥ∗(−t). But this condition can not be satisfied actually in the current interaction theories, so the symmetry of time reversal does not exist actually in the current theories of particle interactions. In the current proo...
We investigate a nonlinear, nonlocal, and fully coupled boundary value problem containing mixed (k,ψ^)-Hilfer fractional derivative (k,ψ^)-Riemann–Liouville integral operators. Existence uniqueness results for the given are proved with aid of standard fixed point theorems. Examples illustrating main presented. The paper concludes some interesting findings.
Let S be a set. For an arithmetical map ψ : Z → S, if for some n ∈ Z = {1, 2, 3, · · · } we have ψ(x+ n) = ψ(x) for all x ∈ Z, then we say that ψ is periodic modulo n and n is a period of ψ. Let P(S) denote the set of all periodic maps ψ : Z → S. If m,n ∈ Z are periods of a map ψ ∈ P(S), then the greatest common divisor (m,n) is also a period of ψ, for we can write (m,n) in the form am + bn wit...
Charm production in antiproton-nucleus collisions at the J/ψ and the ψ ′ thresholds Abstract We discuss the production of charmonium states in antiproton-nucleus collisions at the ψ ′ threshold. It is explained that measurements in ¯ pA collisions will allow to get new information about the strengths of the inelastic J/ψN and ψ ′ N interaction, on the production of Λc and ¯ D in charmonium-nucl...
The production of J/ψ mesons in jets is studied in the forward region of proton-proton collisions using data collected with the LHCb detector at a center-of-mass energy of 13 TeV. The fraction of the jet transverse momentum carried by the J/ψ meson, z(J/ψ)≡p_{T}(J/ψ)/p_{T}(jet), is measured using jets with p_{T}(jet)>20 GeV in the pseudorapidity range 2.5<η(jet)<4.0. The observed z(J/ψ) distri...
We study the time and temperature dependent correlation functions for an impenetrable Bose gas with Neumann or Dirichlet boundary conditions 〈ψ(x1, 0)ψ(x2, t)〉±,T . We derive the Fredholm determinant formulae for the correlation functions, by means of the Bethe Ansatz. For the special case x1 = 0, we express correlation functions with Neumann boundary conditions 〈ψ(0, 0)ψ(x2, t)〉+,T , in terms ...
The ψ ≡ ψ(3770) particle, lying just above DD̄ threshold, is a well-defined source of charmed particle pairs in ee collisions. It is now undergoing high-intensity studies at the CLEO Detector at Cornell [1] and the BES Detector in China [2]. Its couplings to charmless states are of interest for several reasons. (1) The production and decays of ψ depend on its composition of D1, S1, and DD̄ contin...
In this paper, we present a new class of cyclic (noncyclic) α-ψ and β-ψ condensing operators survey the existence best proximity points (pairs) as well coupled in setting reflexive Busemann convex spaces. Then an application main result to study optimal solution for system differential equations is demonstrated.
