A classification is given for regular positions D Ä D D of Jones index 4 where D=alg lim wwÄ M nk (C) is an even matroid algebra and where the individual summands have index 2. A similar classification is obtained for positions of direct sums of 2-symmetric algebras and, in the odd case, for the pos
The concept of a combinatorial W P U -geometry for a Coxeter group W , a subset P of its generating involutions and a subgroup U of W with P ⊆ U yields the combinatorial foundation for a unified treatment of the representation theories of matroids and of even -matroids. The concept of a W P -matroid
Let G be a matroid on ground set . The Orlik-Solomon algebra A G is the quotient of the exterior algebra on by the ideal generated by circuit boundaries. The quadratic closure A G of A G is the quotient of by the ideal generated by the degree-two component of . We introduce the notion of the nbb set
