<div align="left"><b><b><font color="#ff0000">Abstract:</font></b></b><font
color="#ff0000"><font color="#000000"> The collection of
partitions of positive integers, the collection of
Young diagrams and the collection of numerical sets
are in one to one correspondence with each other.
Therefore any concept in one of these collections has
its counterpart in the other collections. For example
the concept of Arf numerical semigroup in the
collection of numerical sets, gives rise to the
concept of Arf partition of a positive integer in the
collection of partitions. Several characterizations of
Arf partitions have been given in recent works. In
this talk we will characterize Arf partitions of
maximal length of positive integers.<br>
This is a joint work with Nesrin Tutaş and Nihal
Gümüşbaş from Akdeniz University.<i><br>
