    Enumerations of bargraphs with respect to corner statistics
    (University of Belgrade, 2020) Mansour, T.; Yıldırım, Gökhan
    We study the enumeration of bargraphs with respect to some corner statistics. We find generating functions for the number of bargraphs that track the corner statistics of interest, the number of cells, and the number of columns. We also consider bargraph representation of set partitions and obtain some explicit formulas for the number of specific types of corners in such representations.
