In this section we prove that any taut bipartite distance-regular graph of odd diameter D ≥ 5 is an antipodal 2-cover.. is said to be antipodal whenever D is a disjoint union

We describe a little the blow–ups of the phase portrait of the intricate point p given in Figure 5. Its first blow–up is given in Figure 6A. In it we see from the upper part of

An important problem in the theory of quadratic forms is to determine when an anisotropic quadratic form ' over F becomes isotropic over the function eld F ( ) of another form.

Once bulk deformation b is chosen (so that there is a torus fiber L whose Floer cohomology is non-vanishing), then we consider the Floer chain complex of L with a generic torus fiber

Rule 5: If there are roots remaining, go to the lowest remaining root, select the leftmost available letter in the appropriate label-group, and repeat Rules 1 through 4, drawing the

For every odd prime power q, there is a unique semifield, up to isotopism, of order q 6 in subclass F 4 (a) which is 3-dimensional over its right nucleus and hence 6- dimensional

In particular, if (S, p) is a normal singularity of surface whose boundary is a rational homology sphere and if F : (S, p) → (C, 0) is any analytic germ, then the Nielsen graph of

Recall that an abelian variety over a field k of characteristic p is said to be supersingular if it is isogenous to a product of supersingular elliptic curves over an algebraic
