On avoidable and unavoidable claws

Xiaoyun Lu, Da-Wei Wang, C.K. Wong
1998 Discrete Mathematics  
We 19 prove that every claw of order n with degree less than ~n appears in every n-vertex tournament. u Thus for large n, the maximum We also construct avoidable claws with degree approaching i3n. tl 2  ...  A claw of degree k is a directed tree consisting of k paths emerging from a common root.  ...  For r,s,t with 3r+2s+t=n-1 and t ~> r, let C(r,s,t) denote the claw whose partition of n-1 has r threes, s twos, and t ones.  ...
