Support theory for Drinfeld doubles of some infinitesimal group schemes [PDF]
Algebra & Number Theory, 2021 Consider a Frobenius kernel G in a split semisimple algebraic group, in very good characteristic. We provide an analysis of support for the Drinfeld center Z(rep(G)) of the representation category for G, or equivalently for the representation category of

Group Decision and Negotiation, 2021 Large-scale group decision-making (LSGDM) deals with complex decision- making problems which involve a large number of decision makers (DMs). Such a complex scenario leads to uncertain contexts in which DMs elicit their knowledge using linguistic ...

The spectral dimension of simplicial complexes: a renormalization group theory [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2019 Simplicial complexes are increasingly used to study complex system structures and dynamics including diffusion, synchronization and epidemic spreading. The spectral dimension of the graph Laplacian is known to determine the diffusion properties at long ...

Two Algorithms in Group Theory [PDF]
Elementary Theory of Groups and Group Rings, and Related Topics, 2018 We present a new algorithm deciding if the intersection of a quasiconvex subgroup of a negatively curved group with a conjugate is finite. We also give a short proof of decidability of the membership problem for quasiconvex subgroups of finitely ...

Group Processes & Intergroup Relations, 2021 Conspiracy beliefs are widespread and can have detrimental consequences. As perceived social norms can exert a powerful influence on individuals, we investigated the relationship between perceived conspiracy belief norms and personal endorsement, and ...

Group testing: an information theory perspective [PDF]
Foundations and Trends in Communications and Information Theory, 2019 The group testing problem concerns discovering a small number of defective items within a large population by performing tests on pools of items. A test is positive if the pool contains at least one defective, and negative if it contains no defectives ...

Codes, Differentially
IEEE Transactions on Information Theory, 2019 Boolean functions, coding theory and $t$ -designs have close connections and interesting interplay. A standard approach to constructing $t$ -designs is the use of linear codes with certain regularity.

Multireference Perturbation Theory with Cholesky Decomposition for the Density Matrix Renormalization Group [PDF]
Journal of Chemical Theory and Computation, 2016 We present a second-order N-electron valence state perturbation theory (NEVPT2) based on a density matrix renormalization group (DMRG) reference wave function that exploits a Cholesky decomposition of the two-electron repulsion integrals (CD-DMRG-NEVPT2).

SgpDec : Cascade (de)compositions of finite transformation semigroups and permutation groups [PDF]
, 2014 We describe how the SgpDec computer algebra package can be used for composing and decomposing permutation groups and transformation semigroups hierarchically by directly constructing substructures of wreath products, the so called cascade products.Final ...

Ruptures and Repairs in Group Psychotherapy: From Theory to Practice
International journal of group psychotherapy, 2021 The group climate, cohesion, and alliance with the leaders are critical elements of effective group psychotherapy. Although there has been significant attention to these curative mechanisms, there has been less attention to ruptures in the group ...
