Vertex-, edge-, and total-colorings of Sierpiński-like graphs

Vertex-colorings, edge-colorings and total-colorings of the Sierpiński gasket graphs S n , the Sierpiński graphs S ( n , k ) , graphs S + ( n , k ) , and graphs S + + ( n , k ) are considered. In particular, χ ″ ( S n ) , χ ′ ( S ( n , k ) ) , χ ( S + ( n , k ) ) , χ ( S + + ( n , k ) ) , χ ′ ( S + ( n , k ) ) , and χ ′ ( S + + ( n , k ) ) are determined.
