... End(T ⊕ T ∗ ), which satisfies both symplectic and complex conditions, i.e. J ∗ = −J (equivalently, orthogonal with respect to the canonical inner product (4.1)) and J 2 = −1. We can show that the obstruction to the existence of a generalized almost complex structure is the same as that for an almos ...

A FIXED POINT THEOREM FOR BOUNDED
... We will prove the theorem for maps, and derive the theorem for flows as a consequence. In fact, many of the definitions and proofs follow analogously for both cases. When that is the case, we will just refer to the “dynamical system,” with the recognition that the statement applies to both flows and ...

Concepts in Algebra and Geometry
... Much of the Algebra sequence that follows is already an informal part of Geometry B. But the formal and specific emphasis on these topics means that we will be unable to cover some of the current Geometry sequence. We believe that the Glencoe text mitigates this sacrifice by ensuring adequate covera ...
