چکیده
We describe a diagrammatic procedure which lifts strict monoidal actions from additive categories to categories of complexes avoiding any use of direct sums. As an application, we prove that every simple transitive 2-representation of the 2-category of projective bimodules over a finite dimensional algebra is equivalent to a cell 2-representation.

For irreducible integrable highest weight modules of the finite and affine Lie algebras of type A and D, we define an isomorphism between the geometric realization of the crystal graphs in terms of irreducible components of Nakajima quiver varieties and the combinatorial realizations in terms of Young tableaux and Young walls. For type A (1) n , we extend the Young wall construction to arbitrar...

Abstract. A theorem of Scott gives an upper bound for the normalized volume of lattice polygons with exactly i > 0 interior lattice points. We will show that the same bound is true for the normalized volume of lattice polytopes of degree 2 even in higher dimensions. The finiteness of lattice polytopes of degree 2 up to standard pyramids and affine unimodular transformation follows from a theore...
متن کاملDinuclear and layered copper 2-pyridylphosphonates with weak ferromagnetism observed in layer compound Cu(C5H4NPO3).
This paper reports the syntheses and structures of three new copper phosphonates based on 2-pyridylphosphonate, namely, Cu(C(5)H(4)NPO(3)H)2 (1), Cu3(OH)2(C(5)H(4)NPO(3))2.2H2O (2) and Cu(C(5)H(4)NPO(3)) (3). Compound 1 has a discrete dimeric structure in which the {CuO(4)N} square pyramids are linked by the {CPO(3)} tetrahedra through corner-sharing. The dimers are further connected into a cha...
متن کاملTHE LIQUID PHASE EPITAXY OF SELF–ASSEMBLED InAsSbP–BASED STRAIN INDUCED ISLANDS ON InAs SUBSTRATES AND THEIR EVOLUTION FROM PYRAMIDS TO QUANTUM DOTS
The Liquid Phase Epitaxy technique has been applied for the formation on InAs (100) substrates self-assembled InAsSbP-based strain induced islands. The evaluation of these objects from pyramids to globe and quantum dots (QD) was detected and investigated. The Scanning Electron Microscope (SEM-EDAX – FEI Nova 600–Dual Beam) and Atomic Force Microscope (AFM – TM Microscopes–Autoprobe CP) equipmen...
