A Note on the Critical Group of a Line Graph [PDF]
The Electronic Journal of Combinatorics, 2011 This note answers a question posed by Levine. The main result shows that under certain circumstances a critical group of a directed graph is the quotient of a critical group of its directed line graph.

Focus groups: From collecting data to critical pedagogical practice [PDF]
Zbornik Instituta za pedagoška istraživanja, 2007 This paper presents the positivist and constructivist theory and practice of focus groups. We pointed out to the paradigmatic differences in notional attributes of focus groups, as well as to the historic circumstances of their appearance.

Cyclic Critical Groups of Graphs
Australas. J Comb., 2015 In this note, we describe a construction that leads to families of graphs whose critical groups are cyclic. For some of these families we are able to give a formula for the number of spanning trees of the graph, which then determines the group exactly. We also pose several open questions related to this work.

A note on the Dancer–Fučík spectra of the fractional p-Laplacian and Laplacian operators
Advances in Nonlinear Analysis, 2015 We study the Dancer–Fučík spectrum of the fractional p-Laplacian operator. We construct an unbounded sequence of decreasing curves in the spectrum using a suitable minimax scheme. For p = 2, we present a very accurate local analysis.

Nonlinear nonhomogeneous Neumann eigenvalue problems
Electronic Journal of Qualitative Theory of Differential Equations, 2015 We consider a nonlinear parametric Neumann problem driven by a nonhomogeneous differential operator with a reaction which is $(p-1)$-superlinear near $\pm\infty$ and exhibits concave terms near zero.

Critical Groups and Partitions of Finite Groups
Mediterranean Journal of MathematicsWe define a class of finite groups based on the properties of the closed twins of their power graphs and study the structure of those groups. As a byproduct, we obtain results about finite groups admitting a partition by cyclic subgroups.

The critical group of a combinatorial map [PDF]
Combinatorial TheoryMotivated by the appearance of embeddings in the theory of chip firing and the critical group of a graph, we introduce a version of the critical group (or sandpile group) for combinatorial maps, that is, for graphs embedded in orientable surfaces. We provide several definitions of our critical group, by approaching it through analogues of the cycle ...

The invariant rings of the Sylow groups of GU(3,q2), GU(4,q2), Sp(4,q) and O+(4,q) in the natural characteristic [PDF]
, 2016 Let G be a Sylow p -subgroup of the unitary groups GU(3,q2)GU(3,q2), GU(4,q2)GU(4,q2), the symplectic group Sp(4,q)Sp(4,q) and, for q odd, the orthogonal group O+(4,q)O+(4,q).

Lost and Finding: Experiences of Newly Graduated Critical Social Workers [PDF]
, 2019 The first year of social work practice can be very stressful for new practitioners. Practice develops in response to the meaning we place on what we do and on our professional goals.
