Involutions Fixing Rp
This paper studies the equivariant cobordism classification of all involutions fixing a disjoint union of an odd-dimensional real projective space RP with its normal bundle nonbounding and a Dold manifold P (h, i) with h > 0 and i > 0. For odd h, the complete analysis of the equivariant cobordism classes of such involutions is given except that the upper and lower bounds on codimension of P (h,...
متن کاملCORRECTIONS TO “ INVOLUTIONS FIXING RP odd P ( h , i ) , II ”
The purpose of this note is to correct statements of some assertions in [1]. The mistake occurs in the argument of the case in which the normal bundle ν over P (h, i) is nonstandard. Specifically, some incorrect calculations first happen in the arguments of the cases u = 0 and u > 1 of page 1309 (in the proof of Lemma 3.4 of [1]). This leads to the loss of the existence of some involutions with...
متن کاملJa n 20 03 On the involutions fixing the class of a lattice
With any integral lattice Λ in n-dimensional euclidean space we associate an elementary abelian 2-group I(Λ) whose elements represent parts of the dual lattice that are similar to Λ. There are corresponding involutions on modular forms for which the theta series of Λ is an eigenform; previous work has focused on this connection. In the present paper I(Λ) is considered as a quotient of some fini...
متن کاملIndecomposable Polytopes
The space of summands (with respect to vector addition) of a convex polytope in n dimensions is studied. This space is shown to be isomorphic to a convex pointed cone in Euclidean space. The extreme rays of this cone correspond to similarity classes of indecomposable polytopes. The decomposition of a polytope is described and a bound is given for the number of indecomposable summands needed. A ...
متن کاملOn the Multiplicative Order of Fn+1/fn modulo Fm
Here, we show that if s �∈ {1, 2, 4} is a fixed positive integer and m and n are coprime positive integers such that the multiplicative order of Fn+1/Fn modulo Fm is s, where Fk is the kth Fibonacci number, then m < 500s2.
