8 Popular Difference Sets

چکیده
We provide further explanation of the significance of an example in a recent paper of Wolf in the context of the problem of finding large subspaces in sumsets. Throughout these notes G will denote the group F2 , that is the n-dimensional vector space over F2, and PG will denote the normalized counting measure on G. The convolution of two functions f, g ∈ L(PG) is defined to be f ∗ g(x) := ∫

We study quadratic residue difference sets, GMW difference sets, and difference sets arising from monomial hyperovals, all of which are (2d−1, 2d−1−1, 2d−2−1) cyclic difference sets in the multiplicative group of the finite field F2d of 2 d elements, with d ≥ 2. We show that, except for a few cases with small d, these difference sets are all pairwise inequivalent. This is accomplished in part b...
متن کاملPOWERSET OPERATOR FOUNDATIONS FOR CATALG FUZZY SET THEORIES
The paper sets forth in detail categorically-algebraic or catalg foundations for the operations of taking the image and preimage of (fuzzy) sets called forward and backward powerset operators. Motivated by an open question of S. E. Rodabaugh, we construct a monad on the category of sets, the algebras of which generate the fixed-basis forward powerset operator of L. A. Zadeh. On the next step, w...
متن کاملTwelfth Power Qualified Residue Difference Sets
Qualified residue difference sets of power n are known to exist for n = 2, 4, 6, as do similar sets that include the zero element, while both classes of set are known to be nonexistent for n = 8 and n = 10. Both classes of set are proved nonexistent for n = 12.

متن کاملOn Mining Fuzzy Classification Rules for Imbalanced Data
Fuzzy rule-based classification system (FRBCS) is a popular machine learning technique for classification purposes. One of the major issues when applying it on imbalanced data sets is its biased to the majority class, such that, it performs poorly in respect to the minority class. However many cases the minority classes are more important than the majority ones. In this paper, we have extended ...
