Minkowski Measure of Asymmetry and Minkowski Distance for Convex BodiesGuo, Qi January 2004 (has links)
<p>This thesis consists of four papers about the Minkowski measure of asymmetry and the Minkowski (or BanachMazur) distance for convex bodies.We relate these two quantities by giving estimates for the Minkowski distance in terms of the Minkowski measure. We also investigate some properties of the Minkowski measure, in particular a stability estimate is given. More specifically, let <i>C</i> and <i>D</i> be ndimensional convex bodies. Denote by As(<i>C</i>) and As(<i>D</i>) the Minkowski measures of asymmetry of <i>C</i> and <i>D </i>resp. and by <i>d</i>(<i>C,D</i>) the Minkowski distance between <i>C</i> and <i>D</i>.</p><p>In Paper I, by using a linearisation method for affine spaces and affine maps and using a generalisation of a lemma of D.R. Lewis, we proved that <i>d</i>(<i>C</i>,<i>D</i>) < <i>n</i>(As(<i>C</i>) + As(<i>D</i>))/2 for all convex bodies <i>C,D</i>.</p><p>In Paper II, by first proving some general existence theorems for a class of volumeincreasing affine maps, we obtain the estimate that under the same conditions as in paper I, <i>d</i>(<i>C,D</i>) < (<i>n</i>1) min(As(<i>C</i>),As(<i>D</i>)) + <i>n</i>.</p><p>In Paper III we consider the Minkowski measure itself. We determine the Minkowski measures for convex hulls of sets of the form <i>conv</i>(<i>C,p</i>) where <i>C</i> is a convex set with known measure of asymmetry and <i>p</i> is a point outside <i>C</i>.</p><p>In Paper IV, we focus on estimating the deviation of a convex body C from the simplex S if the Minkowski measure of C is close to the maximum value n (known to be attained only for the simplex). We prove that if As(C) > n  ε for 0 < ε < 1/δ where δ = 8(n+1), then d(C,S) < 1 + 8(n+1) ε .</p>

We also investigate some properties of the Minkowski measure, in particular a stability estimate is given. More specifically, let C and D be ndimensional convex bodies. Denote by As(C) and As(D) the Minkowski measures of asymmetry of C and D resp. and by d(C,D) the Minkowski distance between C and D. In Paper I, by using a linearisation method for affine spaces and affine maps and using a generalisation of a lemma of D.R. Lewis, we proved that d(C,D) < n(As(C) + As(D))/2 for all convex bodies C,D. In Paper II, by first proving some general existence theorems for a class of volumeincreasing affine maps, we obtain the estimate that under the same conditions as in paper I, d(C,D) < (n1) min(As(C),As(D)) + n. In Paper III we consider the Minkowski measure itself. We determine the Minkowski measures for convex hulls of sets of the form conv(C,p) where C is a convex set with known measure of asymmetry and p is a point outside C. In Paper IV, we focus on estimating the deviation of a convex body C from the simplex S if the Minkowski measure of C is close to the maximum value n (known to be attained only for the simplex). We prove that if As(C) > n  ε for 0 < ε < 1/δ where δ = 8(n+1), then d(C,S) < 1 + 8(n+1) ε .

Optimization and Estimation of Solutions of Riccati EquationsSigstam, Kibret January 2004 (has links)
This thesis consists of three papers on topics related to optimization and estimation of solutions of Riccati equations. We are concerned with the initial value problem f'+f² =r², f(0)=0, (*) and we want to optimise F(T)= ∫0T f(t) dt when r is allowed to vary over the set R(φ ) of all equimeasurable rearrangements of a decreasing function φ and its convex hull CR(φ). In the second paper we give a new proof of a lemma of Essén giving lower and upper bounds for the solution to the above equation, when r is increasing. We also generalize the lemma to a more general equation. It was proved by Essén that the infimum of F(T) over R(φ) and RC(φ) is attained by the solution f of (*) associated to the increasing rearrangement of an element in R(φ). The supremum of F(T) over RC(φ) is obtained for the solution associated to a decreasing function p, though not necessarily the decreasing rearrangement φ, of an element in R(φ). By changing the perspective we determine the function p that solves the supremum problem.
