Let G be a finite abelian group of odd order. Let N* (G) be the unoriented G-bordism group. Let *: Aut(G) — Aut (N* G)) be the homomorphism given by a* ([M, T]) — [M, T⚪(α⁻¹ × 1)] for a e Aut(G) and ...

Algebraic varieties and their automorphism groups lie at the heart of modern algebraic geometry, intertwining deep theoretical concepts with practical applications. Algebraic varieties, defined as the ...

This is a preview. Log in through your library . Abstract THINKER is an automated natural deduction first-order theorem proving program. This paper reports on how it was adapted so as to prove ...

I shall begin by recalling the classical rigidity and super-rigidity theorems for lattices in higher rank Lie groups. I shall then discuss related theorems for mapping class groups of surfaces and ...
