  • Painlevé Analysis and Similarity Reductions for the Magma Equation 
    Harris, S.E.; Clarkson, P.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    In this paper, we examine a generalized magma equation for rational values of two parameters, m and n. Firstly, the similarity reductions are found using the Lie group method of infinitesimal transformations. The Painlevé ...
  • Palais-Smale condition for chiral fields 
    Suvorov, S.G. (Нелинейные граничные задачи, 1999)
    The well known condition of compactness entered by R. Palais and S. Smale| - condition (C) - can be proved traditionally in rare cases, especially if it is considered the problem about critical points for functional f(u), ...
  • Paley-type graphs of order a product of two distinct primes 
    Das, A. (Algebra and Discrete Mathematics, 2019)
    In this paper, we initiate the study of Paley-type graphs ГN modulo N = pq, where p, q are distinct primes of the form 4k + 1. It is shown that ГN is an edge-regular, symmetric, Eulerian and Hamiltonian graph. Also, the ...
  • Parafunctions of triangular matrices and m-ary partitions of numbers 
    Stefluk, S.; Zatorsky, R. (Algebra and Discrete Mathematics, 2016)
    Using the machinery of paradeterminants and parapermanents developed in [2] we get new relations for some number-theoretical functions natural argument that were studied in [3].
  • Para-Grassmannian Coherent and Squeezed States for Pseudo-Hermitian q-Oscillator and their Entanglement 
    Maleki, Y. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    In this paper, q-deformed oscillator for pseudo-Hermitian systems is investigated and pseudo-Hermitian appropriate coherent and squeezed states are studied. Also, some basic properties of these states is surveyed. The ...
  • Para-Grassmann variables and coherent states 
    Cabra, D.C.; Moreno, E.F.; Tanasă, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    The definitions of para-Grassmann variables and q-oscillator algebras are recalled. Some new properties are given. We then introduce appropriate coherent states as well as their dual states. This allows us to obtain a ...
  • Parallelisms & Lie Connections 
    Blázquez-Sanz, D.; Casale, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    The aim of this article is to study rational parallelisms of algebraic varieties by means of the transcendence of their symmetries. The nature of this transcendence is measured by a Galois group built from the Picard-Vessiot ...
  • Parameter estimators of nonlinear quantile regression 
    Ivanov, A.V.; Orlovsky, I.V. (2005)
    We have obtained the asymptotic normality of parameter estimators of a nonlinear quantile regression with nonsymmetric random noise.
  • Parameterizing the Simplest Grassmann-Gaussian Relations for Pachner Move 3-3 
    Korepanov, I.G.; Sadykov, N.M. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    We consider relations in Grassmann algebra corresponding to the four-dimensional Pachner move 3-3, assuming that there is just one Grassmann variable on each 3-face, and a 4-simplex weight is a Grassmann-Gaussian exponent ...
  • Parametrization of extremals of Grötzsch’s problem 
    Tamrazov, P.M. (Український математичний вісник, 2010)
    We give parametric expressions for extremals of Grötzsch’s problem.
  • Partial actions and automata 
    Dokuchaev, M.; Novikov, B.; Zholtkevych, G. (Algebra and Discrete Mathematics, 2011)
    We use the notion of a partial action of a monoid to introduce a generalization of automata, which we call ``a preautomaton''. We study properties of preautomata and of languages recognized by preautomata.
  • Partial Hopf actions, partial invariants and a Morita context 
    Marcelo Muniz S. Alves; Batista, E. (Algebra and Discrete Mathematics, 2009)
    Partial actions of Hopf algebras can be considered as a generalization of partial actions of groups on algebras. Among important properties of partial Hopf actions, it is possible to assure the existence of enveloping ...
  • Partial logarithmic derivatives and distribution of zeros of analytic functions in the unit ball of bounded L-index in joint variables 
    Bandura, A.I.; Skaskiv, O.B. (Український математичний вісник, 2018)
    We obtain the sufficient conditions of boundedness of L-index in joint variables for analytic functions in the unit ball, where L : Cⁿ → Rⁿ₊ is a continuous positive vector-function. They give an estimate of the maximum ...
  • Partial resolutions in monoid cohomology 
    Grillet, P.A. (Algebra and Discrete Mathematics, 2004)
    Partial resolutions are constructed for the EilenbergMacLane cohomology of monoids, with applications to examples.
  • Partial Sums of Two Quartic q-Series 
    Chu, W.; Wang, C. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    The partial sums of two quartic basic hypergeometric series are investigated by means of the modified Abel lemma on summation by parts. Several summation and transformation formulae are consequently established.
  • Particle Motion in Monopoles and Geodesics on Cones 
    Mayrand, M. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    The equations of motion of a charged particle in the field of Yang's SU(2) monopole in 5-dimensional Euclidean space are derived by applying the Kaluza-Klein formalism to the principal bundle R⁸∖{0}→R⁵∖{0} obtained by ...
  • Part III, Free Actions of Compact Quantum Groups on C*-Algebras 
    Schwieger, K.; Wagner, S. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    We study and classify free actions of compact quantum groups on unital C∗-algebras in terms of generalized factor systems. Moreover, we use these factor systems to show that all finite coverings of irrational rotation ...
  • Partitions of groups and matroids into independent subsets 
    Banakh, T.; Protasov, I. (Algebra and Discrete Mathematics, 2010)
    Can the set R∖{0} be covered by countably many linearly (algebraically) independent subsets over the field Q? We use a matroid approach to show that an answer is ``Yes'' under the Continuum Hypothesis, and ``No'' under its ...
  • Partitions of groups into sparse subsets 
    Protasov, I. (Algebra and Discrete Mathematics, 2012)
    A subset A of a group G is called sparse if, for every infinite subset X of G, there exists a finite subset F ⊂ X, such that ∩x∈FxA is finite. We denote by η(G) the minimal cardinal such that G can be partitioned in η(G) ...
  • Partitions of groups into thin subsets 
    Protasov, I. (Algebra and Discrete Mathematics, 2011)
    Let G be an infinite group with the identity e, κ be an infinite cardinal ≤|G|. A subset A⊂G is called κ-thin if |gA∩A|≤κ for every g∈G∖{e}. We calculate the minimal cardinal μ(G,κ) such that G can be partitioned in μ(G,κ) ...
