It is shown that the graph kc, (consisting of k 4-cycles) has an a-valuation (a stronger form of the graceful valuation) for every positive integer k # 3. The graph 3C, is known to be graceful but it does not have an a-valuation.

## Abstract Let __K__ be the quotient field of a 2โdimensional regular local ring (__R, m__) and let __v__ be a prime divisor of __R__, i.e., a valuation of __K__ birationally dominating __R__ which is residually transcendental over __R__. Zariski showed that: such prime divisor __v__ is uniquely a
We construct a small non-Hamiltonian 3-connected trivalent planar graph whose faces are all 4-gons or 7-gons and show that the shortness coefficient of the class of such graphs is less than one. Then, by transforming non-Hamiltonian trivalent graphs into regular graphs of valency four or five, we ob
## Abstract Chvรกtal and Erdรถs showed that a __k__โconnected graph with independence number at most __k__ and order at least three is hamiltonian. In this paper, we show that a graph contains a 2โfactor with two components, i.e., the graph can be divided into two cycles if the graph is __k__(โฅ 4)โco
It is shown that, if q >/29 and q ~ 0 (mod 3), the infinite class of 5-regular 3-polytopal graphs whose edges are incident with either two triangles or a triangle and a q-gon contains nonhamiltonian members and even has shortness exponent less than one.
