โœฆ Synopsis


A. E. Brouwer has shown that the universal embedding of the U 2n (2) dual polar space has dimension at least (4 n +2)/3 and has conjectured equality. The present paper proves this conjecture by establishing a related result about permutation modules for GL n (4). The method is the same used in the author's previous paper on an analogous question for the Sp 2n (2) dual polar space.

A. E. Brouwer has shown that the universal embedding of the Sp 2n (2) dual polar space has dimension at least (2 n +1)(2 n&1 +1)ร‚3 and has conjectured equality. The present paper settles this conjecture in the affirmative by proving a theorem about permutation modules for GL n (2) which implies the

It is demonstrated that the dual polar space of type Sp(2n, 2) can be generated as a geometry by 3 points when n = 4 and 5. In the latter case this affirmatively resolves a conjecture of Brouwer that the dimension of the universal projective embedding of this geometry is ฮป(5).

It is demonstrated that the generating rank of the dual polar space of type U 2n (q 2 ) is 2n n when q > 2. It is also shown that this is equal to the embedding rank of this geometry.
