Deformations of the discrete Heisenberg group
(Japan AcadTokyoJapão, 2013)
Symmetry and Inverse Closedness for Some Banach ∗-Algebras Associated to Discrete Groups
(Tusi Mathematical Research Group, 2015)
A discrete group G is called rigidly symmetric if for every C*-algebra A the projective tensor product l(1)(G)(circle times) over capA is a symmetric Banach *-algebra. For such a group we show that the twisted crossed ...
On global controllability of discrete-time control systems
(Springer-verlag London LtdGodalmingInglaterra, 1995)
Discrete generator coordinate: Symmetry restoration in finite-dimensional spaces
Group theoretical-based techniques and fundamental results from number theory are used in order to allow for the construction of exact projectors in finite-dimensional spaces. These operators are shown to make use only of ...
The truss‐like discrete element method in fracture and damage mechanics
(Emerald Group Publishing Limited, 2011-12)
Purpose: It is the purpose of this paper to further develop the truss-like discrete element method (DEM) in order to make it suitable to deal with damage and fracture problems. Design/methodology/approach: Finite and ...
Homological invariants for pro-p groups and some finitely presented pro-l groups
(Springer WienWienAustria, 2005)
Controllability of discrete-time control system on the symplectic group
(Elsevier Science BvAmsterdamHolanda, 2001)
Toda lattice field theories, discrete W algebras, Toda lattice hierarchies and quantum groups
In analogy with the Liouville case we study the sl3 Toda theory on the lattice and define the relevant quadratic algebra and out of it we recover the discrete W3 algebra. We define an integrable system with respect to the ...
Discrete-event simulation guides pipeline logistics
(Pennwell Publ Co Energy Group, 2011-08)
The management of oil-product pipelines represents a critical task in the daily operation of petroleum supply chains. Efficient computational tools are needed to perform this activity in a reliable and cost-effective manner. ...
