  • Some remarks on symplectic injective stability 
    BASU, RABEYA; Rao, Ravi A.; Chattopadhyay, Pratyusha (American Mathematical Society, 2011-01)
    It is shown that if $ A$ is an affine algebra of odd dimension $ d$ over an infinite field of cohomological dimension at most one, with $ (d +1)! A = A$, and with $ 4\vert(d -1)$, then Um $ _{d+1}(A) = e_1\textrm{Sp}_{d+1}(A)$. ...
  • Risk Minimizing Option Pricing for a Class of Exotic Options in a Markov-Modulated Market 
    Basak, Gopal K.; Ghosh, Mrinal K.; GOSWAMI, ANINDYA (Taylor & Francis, 2011-02)
    We address risk minimizing option pricing in a regime switching market where the floating interest rate depends on a finite state Markov process. The growth rate and the volatility of the stock also depend on the Markov ...
  • Real and strongly real classes in PGLn(q) and quasi-simple covers of PSLn(q) 
    Gill, Nick; SINGH, ANUPAM KUMAR (De Gruyter, 2011-05)
    We classify the real and strongly real conjugacy classes in PGLn(q), PSLn(q), and all quasi-simple covers of PSLn(q). In each case we give a formula for the number of real, and the number of strongly real, conjugacy ...
  • Real and strongly real classes in SLn(q) 
    Gill, Nick; SINGH, ANUPAM KUMAR (De Gruyter, 2011-05)
    We classify the real and strongly real conjugacy classes in GLn(q) and SLn(q). In each case we give a formula for the number of real, and the number of strongly real, conjugacy classes.This paper is the first of two that ...
  • Absence of torsion for NK_1(R) over associative rings 
    BASU, RABEYA (World Scientific Publishing, 2011-07)
    When R is a commutative ring with identity, and if k ∈ ℕ, with kR = R, then it was shown in [C. Weibel, Mayer–Vietoris Sequence and Module Structure on NK0, Lecture Notes in Mathematics, Vol. 854 (Springer, 1981), pp. ...
  • Real Elements and Schur Indices of a Group 
    Kulshrestha, Amit; SINGH, ANUPAM KUMAR (Indian Mathematical Society, 2011-11)
    In this article we try to explore the relation between real conjugacy classes and real characters of finite groups at more refined level. This refinement is in terms of properties of groups such as strong reality and total ...
  • Stable trace formulas and discrete series multiplicitie 
    SPALLONE, STEVEN (Mathematical Sciences Publishers, 2012-01)
    Let G be a reductive algebraic group over ℚ, and suppose that Γ ⊂ G(ℝ) is an arithmetic subgroup defined by congruence conditions. A basic problem in arithmetic is to determine the multiplicities of discrete series ...
  • 3-Way Software Testing with Budget Constraints 
    MAITY, SOUMEN (Institute of Electronics, Information and Communication Engineers, 2012-01)
    In most software development environments, time, computing and human resources needed to perform the testing of a component is strictly limited. In order to deal with such situations, this paper proposes a method of creating ...
  • Distribution of zeta zeroes of Artin–Schreier covers 
    Bucur, A.; Chantal, D.; Feigon, B.; Matilde Lalín; SINHA, KANEENIKA (International Press, 2012-01)
    We study the distribution of the zeroes of the zeta functions of the family of Artin–Schreier covers of the projective line over Fq when q is fixed and the genus goes to infinity. We consider both the global and the ...
  • Local analytic conjugacy of semi-hyperbolic mappings in two variables, in the non-archimedean setting 
    Jenkins, Adrian; SPALLONE, STEVEN (World Scientific Publishing, 2012-04)
    In this note, we consider locally invertible analytic mappings of a two-dimensional space over a non-archimedean field. Such a map is called semi-hyperbolic if its Jacobian has eigenvalues λ1 and λ2 so that λ1 = 1 and |λ2| ...
