Decomposing plane cubic graphs
It was conjectured by Hoffmann-Ostenhof that the edge set of every cubic graph can be decomposed into a spanning tree, a matching and a family of cycles. We prove the conjecture ...

Small circulant complex Hadamard matrices of Butson type
We study the circulant complex Hadamard matrices of order n whose entries are l-th roots of unity. For n = l prime we prove that the only such matrix, up to equivalence, is the Fou...

Complexity of short rectangles and periodicity
The Morse-Hedlund Theorem states that a bi-infinite sequence η in a finite alphabet is periodic if and only if there exists n ∈ N such that the block complexity function Pη(n...

Harvesting Training Images for Fine-Grained Object Categories Using Visual Descriptions
We harvest training images for visual object recognition by casting it as an IR task. In contrast to previous work, we concentrate on fine-grained object categories, such as the l...
