    The purpose of this paper is to determine all maximal graded subalgebras of the four infinite series of finite-dimensional graded Lie superalgebras of odd Cartan type over an algebraically closed field of characteristic p>3p>3. All maximal graded subalgebras consist of three types (\MyRoman{1}), (\MyRoman{2}) and (\MyRoman{3}). Maximal graded subalgebras of type (\MyRoman{3}) fall into reducible maximal graded subalgebras and irreducible maximal graded subalgebras. In this paper we classify maximal graded subalgebras of types (\MyRoman{1}), (\MyRoman{2}) and reducible maximal g raded subalgebras.The classification of irreducible maximal graded subalgebras is reduced to that of the irreducible maximal subalgebras of the classical Lie superalgebra p(n)\mathfrak{p}(n).Comment: For the final version, see Transformation Groups 20(4)(2015)1075--110

    The transverse momentum spectra of J/ψJ/\psi, ψ(2S)\psi(2S), and Υ(nS,n=1,2,3)\Upsilon(nS, n=1,2,3) produced in proton-proton (pp+pp), proton-antiproton (pp+pˉ\bar{p}), proton-lead (pp+Pb), gold-gold (Au+Au), and lead-lead (Pb+Pb) collisions over a wide energy range are analyzed by the (two-component) Erlang distribution, the Hagedorn function (the inverse power-law), and the Tsallis-Levy function. The initial temperature is obtained from the color string percolation model due to the fit by the (two-component) Erlang distribution in the framework of multisource thermal model. The excitation functions of some parameters such as the mean transverse momentum and initial temperature increase from dozens of GeV to above 10 TeV. The mean transverse momentum and initial temperature decrease (increase slightly or do not change obviously) with the increase of rapidity (centrality). Meanwhile, the mean transverse momentum of Υ(nS,n=1,2,3)\Upsilon(nS, n=1,2,3) is larger than that of J/ψJ/\psi and ψ(2S)\psi(2S), and the initial temperature for Υ(nS,n=1,2,3)\Upsilon(nS, n=1,2,3) emission is higher than that for J/ψJ/\psi and ψ(2S)\psi(2S) emission, which shows a mass-dependent behavior.Comment: 26 pages, 12 figures.
