ASU Electronic Theses and Dissertations
This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.
In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.
Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries. For more information or questions about this collection contact or visit the Digital Repository ETD Library Guide or contact the ASU Graduate College at gradformat@asu.edu.

is the subposet of An induced by the c-sortable elements, and the m-eralized Cambrian
lattice corresponding to c, denoted Cambm(c), is dened as a subposet of the
braid group accompanied with the right weak ordering induced by the c-sortable elements
under certain conditions. Both of these families generalize the well-studied
Tamari lattice Tn rst introduced by D. Tamari in 1962. S. Fishel and L. Nelson
enumerated the chains of maximum length of Tamari lattices.
In this dissertation, I study the chains of maximum length of the Cambrian and
m-eralized Cambrian lattices, precisely, I enumerate these chains in terms of other
objects, and then nd formulas for the number of these chains for all m-eralized
Cambrian lattices of A1, A2, A3, and A4. Furthermore, I give an alternative proof
for the number of chains of maximum length of the Tamari lattice Tn, and provide
conjectures and corollaries for the number of these chains for all m-eralized Cambrian
lattices of A5.
