T-Tetrominos in Arithmetic Progression
Emily Feller, Robert Hochberg
A famous result of D. Walkup is that an rectangle may be tiled by T-tetrominos if and only if both and are multiples of 4. The "if" portion may be proved by til…
Discrepancy One among Homogeneous Arithmetic Progressions
Robert Hochberg, Paul Phillips
We investigate a restriction of Paul Erdos' well-known problem from 1936 on the discrepancy of homogeneous arithmetic progressions. We restrict our attention to a finite set S of h…
The Gap Number of the T-Tetromino
Robert Hochberg
A famous result of D. Walkup states that the only rectangles that may be tiled by the T-tetromino are those in which both sides are a multiple of four. In this paper we examine the…
Short Proofs for Cut-and-Paste Sorting of Permutations
Daniel Cranston, I. Hal Sudborough, Douglas B. West
We consider the problem of determining the maximum number of moves required to sort a permutation of using cut-and-paste operations, in which a segment is cut out and then pa…
