Summary
As a first application we compute the Lefschetz coincidence number of maps between manifolds\(\mathcal{M}\) whose rational singular cohomologyH*\((\mathcal{M};\mathbb{Q})\) has a simple system of generators.
For the second let\(\mathcal{M}\) be anH-manifold with multiplicationm. Define for\(x \in \mathcal{M}\),m 2 (x,x)=m(x,x) andm k (x)=m(x,m k−1 (x)), for allk>2. All roots of equationm k (x)=m 8 (x),k>s such thatm k (x)=m 3 (x) butm i (x)≠m j (x) for allk>i>j,s≥j≥0 andk−s does not dividei−j, split into a finite number of equivalence classes. We compute precisely the numbers of classes such that their members satisfy the above property.
