Five-list-coloring graphs on surfaces III. One list of size one and one list of size two

Let G be a plane graph with outer cycle C and let (L(v) : v ∈ V (G)) be a family of nonempty sets. By an L-coloring of G we mean a (proper) coloring φ of G such that φ(v) ∈ L(v) for every vertex v of G. Thomassen proved that if v1, v2 ∈ V (C) are adjacent, L(v1) ̸= L(v2), |L(v)| ≥ 3 for every v ∈ V (C)−{v1, v2} and |L(v)| ≥ 5 for every v ∈ V (G)−V (C), thenG has an L-coloring. What happens when ...

Craft Specialization at Shahdad: Pottery Production during the third millennium BC

Many potteries have been discovered from excavations and a surface survey at Shahdad, but few works have beendone to examine craft specialization in pottery production at this important site. Different types of potteries, some ofwhich bearing potter marks demonstrate that craftsmen of the site had involved in manufacturing of centralized potteryproduction. A number of kilns and many waste of po...

Knowledge of Planets in the Third Millennium BC

Recent advances in archaeology, chronobiology, and history of science have made it possible to decipher hitherto obscure passages related to planets in the Indian books of the third millennium BC. A brief summary of this knowledge is presented. It is argued that the period of Mercury was obtained near the end of the Vedic age in India. This was celebrated in terms of the famous myth of Vishnu s...

Beyond One Third Byzantine Failures

The Byzantine agreement problem requires a set of n processes to agree on a value sent by a transmitter, despite a subset of b processes behaving in an arbitrary, i.e. Byzantine, manner and sending corrupted messages to all processes in the system. It is well known that the problem has a solution in a (an eventually) synchronous message passing distributed system iff the number of processes in ...
