Solutions to problems about potentially Ks,t-bigraphic pair
Open Mathematics, 2022 Let S=(a1,…,am;b1,…,bn)S=\left({a}_{1},\ldots ,{a}_{m};\hspace{0.33em}{b}_{1},\ldots ,{b}_{n}), where a1,…,am{a}_{1},\ldots ,{a}_{m} and b1,…,bn{b}_{1},\ldots ,{b}_{n} are two nonincreasing sequences of nonnegative integers. The pair S=(a1,…,am;b1,…,bn)S=

A Gale–Ryser type characterization of potentially
Discrete Mathematics, 2012 AbstractLet A and B be nonincreasing lists of nonnegative integers, having lengths m and n, respectively. The pair (A;B) is potentially Ks,t-bigraphic if there is a simple bipartite graph containing Ks,t (with s vertices in the part of size m and t in the part of size n) such that the lists of vertex degrees in the two partite sets are A and B. We give

A Constructive Extension of the Characterization on Potentially Ks,t-Bigraphic Pairs
Discussiones Mathematicae Graph Theory, 2017 Let Ks,t be the complete bipartite graph with partite sets of size s and t. Let L1 = ([a1, b1], . . . , [am, bm]) and L2 = ([c1, d1], . . . , [cn, dn]) be two sequences of intervals consisting of nonnegative integers with a1 ≥ a2 ≥ . . . ≥ am and c1 ≥ c2

Bigraphic pairs with a realization containing a split bipartite-graph
Czechoslovak Mathematical Journal, 2019 Let Ks,t be the complete bipartite graph with partite sets {x1,…, xs} and {y1,…, yt}. A split bipartite-graph on (s + s′) + (t +t′) vertices, denoted by SBs+s′,t+t′, is the graph obtained from Ks,t by adding s′ + t′ new vertices xs+1,…, xs+s′, yt+1,…, yt+

Language contact in South Oscan epigraphy [PDF]
, 2014 This thesis examines evidence for language contact between Oscan and Greek in the corpus of Oscan inscriptions from Lucania, Bruttium and Messana. These inscriptions were written in an adapted form of the Greek alphabet from around the fourth to first ...
