[ABSTRAK Pada tesis ini dibahas radius spektral minimal untuk graf n simpul berdiameter1, kemudian graf n simpul berdiameter 2 dan graf n simpul berdiameter 3.Pada graf berdiameter 1 dibahas untuk semua nilai n, tetapi untuk grafberdiameter 2 dan 3 yang dibahas hanya untuk banyaknya simpul n < 8. Hasilyang diperoleh adalah graf n simpul dengan diameter 1 memiliki radiusspektral minimal n ? 1 dan graf n simpul dengan diameter 2 memiliki radiusspektral minimal. ABSTRACT In this thesis we told about the minimal spectral radius for graphs n verticeswith diameter 1, graphs n vertices with diameter 2 and graphs n vertices withdiameter 3. For the graphs n vertices with diameter 1, we explored for all of nvalues. But for the graphs with diameters 2 and 3 we explored for n < 8. Theresults are the minimal spectral radius for graphs n vertices with diameter 1equals n ? 1 and the minimal spectral radius for graphs n vertices withdiameter 2 equals .;In this thesis we told about the minimal spectral radius for graphs n verticeswith diameter 1, graphs n vertices with diameter 2 and graphs n vertices withdiameter 3.
