On the Spectra of Certain Classes of
نویسنده
چکیده
In this paper we study the spectra of certain classes of Room frames. The three spectra are incomplete Room squares, uniform Room frames and Room frames of type 2 u t 1. These problems have been studied in numerous papers over the years; in this paper, we complete the three spectra except for one possible exception in each case. Math reviews classiication: 05B15

INTEGER-MAGIC SPECTRA OF CYCLE RELATED GRAPHS
For any h in N , a graph G = (V, E) is said to be h-magic if there exists a labeling l: E(G) to Z_{h}-{0} such that the induced vertex set labeling l^{+: V(G) to Z_{h}} defined by l^{+}(v)= Summation of l(uv)such that e=uvin in E(G) is a constant map. For a given graph G, the set of all for which G is h-magic is called the integer-magic spectrum of G and is denoted by IM(G). In this paper, the ...

متن کاملTHE SPECTRAL DETERMINATION OF THE MULTICONE GRAPHS Kw ▽ C WITH RESPECT TO THEIR SIGNLESS LAPLACIAN SPECTRA
The main aim of this study is to characterize new classes of multicone graphs which are determined by their signless Laplacian spectra. A multicone graph is defined to be the join of a clique and a regular graph. Let C and K w denote the Clebsch graph and a complete graph on w vertices, respectively. In this paper, we show that the multicone graphs K w ▽C are determined by their signless ...
