The notion of a saddle surface is well known in Euclidean space. In this work we extend the idea of a saddle surface to geodesically connected metric spaces. We prove that every energy minimizing surface in a nonpositively ...

This thesis is to study the expected difference of the continuous supremum and discrete maximum of a Lévy process that is often used in finance. We will show that the expected difference is a quantity that highly depends ...

Let (M,g) be a noncompact complete Riemannian manifold whose scalar curvature S(x) is positive for all x in M. In this thesis, we study a conformal deformation of the given metric g, which makes the scalar curvature of the ...

The Schanuel class consists of functions that can be obtained from $\doubc$, the variable z, and closed under addition, multiplication and exponentiation by the exponential function. A proof is presented that the minimum ...

We also prove that the map$$v\to u=v\partial\sbsp{\bar z}{-1}v\sb{z}-v\sb{z}$$where $z=x+\sigma y,\ \bar z=x-\sigma y$ (when $\sigma=1$ this applies to the case I and when $\sigma=i$ to case II) maps a solution of the ...

In [20], Keith and Zhong prove that spaces admitting Poincar e inequalities also admit a priori stronger Poincar e inequalities. We use their technique, with slight adjustments, to obtain a similar result in the case of ...

Assume M is a connected, compact 6-dimensional symplectic manifold equipped with a semi-free Hamiltonian circle action such that the fixed point set consists of isolated points or compact orientable surfaces. Assume the ...

A semigroup T(,t) : t (GREATERTHEQ) 0 of composition operators on H('P)( ) arises as T(,t)(f) = f(CCIRC)(phi)(,t) where (phi)(,t) : t (GREATERTHEQ) 0 is a semigroup of analytic functions mapping the unit disk ...

In this dissertation we deﬁne and study a two-parameter family of recursive sequences which we call the bow sequences. The general bow sequence is deﬁned similarly to the Stern sequence, and many of the properties of the ...
