A computer search of maximal partial spreads in PG(3,q)
In this work we find new minimum sizes for the maximal partial spreads of
PG, for and for every such that .
Furthermore, for and 27 we find all the unknown sizes between our
minimums and the value . Moreover, we obtain density results also in
the cases and , already studied but not yet completed. Finally, we
find the known exceptional size 45 for .Comment: 10 page
New results on maximal partial line spreads in PG(5,q)
In this work, we prove the existence of maximal partial line spreads in
PG(5,q) of size q^3+q^2+kq+1, with 1 \leq k \leq (q^3-q^2)/(q+1), k an integer.
Moreover, by a computer search, we do this for larger values of k, for q \leq
7. Again by a computer search, we find the sizes for the largest maximal
partial line spreads and many new results for q \leq 5
A new class of maximal partial spreads in PG(4,q)
In this work we construct a new class of maximal partial spreads in
, that we call -added maximal partial spreads. We obtain them by
depriving a spread of a hyperplane of some lines and adding lines not of
the hyperplane for each removed line. We do this in a theoretic way for every
value of , and by a computer search for an odd prime and .
More precisely we prove that for every there are -added maximal partial
spreads from the size to the size , while by a computer
search we get larger cardinalities.Comment: 17 page
