  • S¹-Bott functions on manifolds 
    Repovš, D.; Sharko, V. (Український математичний журнал, 2012)
    We study S¹-Bott functions on compact smooth manifolds. In particular, we investigate S¹-invariant Bott functions on manifolds with circle action.
  • Sard’s theorem for mappings between Fréchet manifolds 
    Eftekharinasab, K. (Український математичний журнал, 2010)
    We prove an infinite-dimensional version of Sard’s theorem for Fréchet manifolds. Let M (respectively, N) be a bounded Fréchet manifold with compatible metric d M (respectively, d N ) modeled on Fréchet spaces E (respectively, ...
  • Scalar Flat Kähler Metrics on Affine Bundles over CP¹ 
    Honda, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    We show that the total space of any affine C-bundle over CP¹ with negative degree admits an ALE scalar-flat Kähler metric. Here the degree of an affine bundle means the negative of the self-intersection number of the section ...
  • Scale-Dependent Functions, Stochastic Quantization and Renormalization 
    Altaisky, M.V. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    We consider a possibility to unify the methods of regularization, such as the renormalization group method, stochastic quantization etc., by the extension of the standard field theory of the square-integrable functions ...
  • Scattered Subsets of Groups 
    Banakh, T.O.; Protasov, I.V.; Slobodianiuk, S.V. (Український математичний журнал, 2015)
    We define scattered subsets of a group as asymptotic counterparts of the scattered subspaces of a topological space and prove that a subset A of a group G is scattered if and only if A does not contain any piecewise shifted ...
  • Scattering of electromagnetic waves in an accelerating section of a supercollider 
    Bogomolov, Ya.L.; Semenov, E.S.; Yunakovsky, A.D. (Нелинейные граничные задачи, 2006)
  • Schreier Graphs for a Self-Similar Action of the Heisenberg Group 
    Bondarenko, I.; Kravchenko, R. (Український математичний журнал, 2013)
    We construct a faithful self-similar action of the discrete Heisenberg group with the following properties: This action is self-replicating, finite-state, level-transitive, and noncontracting. Moreover, there exist orbital ...
  • Schrödinger-like Dilaton Gravity 
    Nakayama, Yu (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    We investigate possibilities for a Schrödinger-like gravity with the dynamical critical exponent z=2, where the action only contains the first-order time derivative. The Horava gravity always admits such a relevant deformation ...
  • Schrödinger Operators with Purely Discrete Spectrum 
    Simon, B. (2009)
    We prove that −Δ+V has purely discrete spectrum if V ≥ 0 and, for all M, |{x | V (x)<M}| < ∞ and various extensions.
  • Schur Positivity and Kirillov-Reshetikhin Modules 
    Fourier, G.; Hernandez, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    In this note, inspired by the proof of the Kirillov-Reshetikhin conjecture, we consider tensor products of Kirillov-Reshetikhin modules of a fixed node and various level. We fix a positive integer and attach to each of its ...
  • Schur Superpolynomials: Combinatorial Definition and Pieri Rule 
    Blondeau-Fournier, O.; Mathieu, P. (Symmetry, Integrability and Geometry: Methods and Applications, 2015)
    Schur superpolynomials have been introduced recently as limiting cases of the Macdonald superpolynomials. It turns out that there are two natural super-extensions of the Schur polynomials: in the limit q=t=0 and q=t→∞, ...
  • Schwarz boundary-value problems for solutions of a generalized Cauchy-Riemann system with a singular line 
    Plaksa, S.A. (Український математичний вісник, 2019)
    We consider a generalized Cauchy–Riemann system with a rectilinear singular interval of the real axis. Schwarz boundary value problems for generalized analytic functions which satisfy the mentioned system are reduced to ...
  • Schwinger-Fronsdal Theory of Abelian Tensor Gauge Fields 
    Guttenberg, S.; Savvidy, G. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    This review is devoted to the Schwinger and Fronsdal theory of Abelian tensor gauge fields. The theory describes the propagation of free massless gauge bosons of integer helicities and their interaction with external ...
  • S-conditionally permutable subgroups and p-nilpotency of finite groups 
    Xu, Y.; Li, X.H. (Український математичний журнал, 2014)
    We study the p-nilpotency of a group such that every maximal subgroup of its Sylow p-subgroups is s-conditionally permutable for some prime p. By using the classification of finite simple groups, we get interesting new ...
  • Second-Order Approximate Symmetries of the Geodesic Equations for the Reissner-Nordström Metric and Re-Scaling of Energy of a Test Particle 
    Hussain, I.; Mahomed, F.M.; Qadir, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2007)
    Following the use of approximate symmetries for the Schwarzschild spacetime by A.H. Kara, F.M. Mahomed and A. Qadir (Nonlinear Dynam., to appear), we have investigated the exact and approximate symmetries of the system of ...
  • Second-Order Conformally Equivariant Quantization in Dimension 1|2 
    Mellouli, N. (Symmetry, Integrability and Geometry: Methods and Applications, 2009)
    This paper is the next step of an ambitious program to develop conformally equivariant quantization on supermanifolds. This problem was considered so far in (super)dimensions 1 and 1|1. We will show that the case of several ...
  • Second order Linear Differential Equations of Fuchsian Type with Four Singularities 
    Lukashevich, N.A. (Нелінійні коливання, 2001)
    We study a system of linear singularly perturbed functional differential equations by the method of integral manifolds. We construct a change of variables that decomposes this system into two subsystems, an ordinary ...

    A.Di Bartolomeo; Quartieri, J.; Steri, S. (Нелінійні коливання, 2003)
    In this paper a general second order Cauchy problem in four dimensional space is considered and sufficient conditions for integrability with generalized Lie series method are determined.
  • Second order nonlinear differential equations with an infinite set of periodic solutions 
    Kiguradze, I.T. (Нелінійні коливання, 2008)
    For the differential equation u′′ = f(t, u, u′), where the function f : R × R² → R is periodic in the first argument and f(t, x, 0) ≡ 0, sufficient conditions for the existence of a continuum of nonconstant periodic solutions ...
