(2000)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 ...

(1994)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 ...

(1992)We present four algorithms that use either scaling or interior point methods for convex optimization problems; two of the algorithms use both.

(1993)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 ...

(1997)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 ...

(2003)Assume M is a connected, compact 6dimensional symplectic manifold equipped with a semifree Hamiltonian circle action such that the fixed point set consists of isolated points or compact orientable surfaces. Assume the ...

(1985)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 ...

(1988)A new algorithm is proposed for the detection of small, barely discernible moving objects of unknown position and velocity in a sequence of digital images. First, statistically robust prewhitening techniques are used to ...

(1992)Timefrequency representations are multidimensional transformations that indicate the joint timefrequency content of a signal. Representations such as the wavelet transform, the shorttime Fourier transform, and the Wigner ...

(2002)This thesis considers upper and lower bounds on the density of finite Sidon sets and the use of generating functions and symmetry groups in the analysis of Beatty sequences. This work is available free of charge in PDF and ...

(1995)A sieve is a device for estimating the size of a finite set of integers after certain residue classes have been eliminated. In the sieve theories of RosserIwaniec and DiamondHalberstamRichert, the upper and lower bound ...
