... 2-matroids Let Q 1 and Q 2 be 2-matroids. When Q 1 and Q 2 have the same ground-set and skew classes we shall use Q 1 + Q 2 to denote the parity system which is the sum of Q 1 and Q 2 . When Q 1 and Q 2 have ... since r 1 (A) ≤ r t 1 (A) ≤ r 1 (A) + 1 and r 1 (A) ≤ r ˜ t 1 (A) ≤ r 1 (A) + 1. Parity Systems and the Delta-Matroid Intersection Problem Andr´e Bouch...

... closed, and convex subsets of the bounded and convex set coC, then µ(C n ) = 0 (n ∈ N), and therefore C ∞ = ∅. Appealing again to the ˇ Smulian theorem [6, Theorem V.6.2] we find that the convex ... denotes the closed and convex hull of A and H(C, D) is the Hausdorff-Pompeiu distance between the bounded subsets C and D of X. The E-L measure of nonconvexity was introdu...
