## Abstract It is proved that all classes of polygon trees are characterized by their chromatic polynomials, and a characterization is given of those polynominals that are chromatic polynomials of outerplanar graphs. The first result yields an alternative proof that outerplanar graphs are recogniza

## Abstract In this paper we obtain chromatic polynomials of connected 3‐ and 4‐chromatic planar graphs that are maximal for positive integer‐valued arguments. We also characterize the class of connected 3‐chromatic graphs having the maximum number of __p__‐colorings for __p__ ≥ 3, thus extending a
## Abstract In this paper we obtain chromatic polynomials __P(G__; λ) of 2‐connected graphs of order __n__ that are maximum for positive integer‐valued arguments λ ≧ 3. The extremal graphs are cycles __C__~__n__~ and these graphs are unique for every λ ≧ 3 and __n__ ≠ 5. We also determine max{__P(
We give a matrix generalization of the family of exponential polynomials in one variable , k (x). Our generalization consists of a matrix of polynomials 8 k (X)= (8 (k) i, j (X)) n i, j=1 depending on a matrix of variables X=(x i, j ) n i, j=1 . We prove some identities of the matrix exponential pol
## Abstract In the set of graphs of order __n__ and chromatic number __k__ the following partial order relation is defined. One says that a graph __G__ is less than a graph __H__ if __c__~__i__~(__G__) ≤ __c__~__i__~(__H__) holds for every __i__, __k__ ≤ __i__ ≤ __n__ and at least one inequality is
