  text: "The extension of extremal combinatorics to the setting of exterior algebra
    is a work\r\nin progress that gained attention recently. In this thesis, we study
    the combinatorial structure of exterior algebra by introducing a dictionary that
    translates the notions from the set systems into the framework of exterior algebra.
    We show both generalizations of celebrated Erdös--Ko--Rado theorem and Hilton--Milner
    theorem to the setting of exterior algebra in the simplest non-trivial case of
    two-forms.\r\n"

  text: The celebrated Erdős–Ko–Rado theorem about the maximal size of an intersecting
    family of r-element subsets of  was extended to the setting of exterior algebra
    in [5, Theorem 2.3] and in [6, Theorem 1.4]. However, the equality case has not
    been settled yet. In this short note, we show that the extension of the Erdős–Ko–Rado
    theorem and the characterization of the equality case therein, as well as those
    of the Hilton–Milner theorem to the setting of exterior algebra in the simplest
    non-trivial case of two-forms follow from a folklore puzzle about possible arrangements
    of an intersecting family of lines.

  text: We determine the unique factorization of some polynomials over a finite local
    commutative ring with identity explicitly. This solves and generalizes the main
    conjecture of Qian, Shi and Solé in [13]. We also give some applications to enumeration
    of certain generalized double circulant self-dual and linear complementary dual
    (LCD) codes over some finite rings together with an application in asymptotic
    coding theory.
acknowledgement: The authors would like to thank Prof. Dr. Minjia Shi for bringing
  [13, Conjecture 3.5] to our attention. We would also like to thank the associate
  editor and anonymous reviewers for their valuable comments and suggestions which
  improved and clarified the manuscript.
