Supermodular utility representations
… it is well-known that existence of supermodular representations is equivalent to existence of quasisupermodular ones for monotone preferences. In particular, strictly monotone preferences admit a supermodular representation. This paper revisits the axiomatic foundations of supermodularity of …

Compact 3D Representations
The need to compactly represent 3D data is motivated by the ever-increasing size of these data. Furthermore, for large data sets it is useful to randomly access and process a small part of the data. In this thesis we propose two methods of compactly representing 3D data while allowing random …

Interpretable Network Representations
… introduce our method on interpretable network representations: the network shape. It provides a framework to represent a network with a 3-dimensional shape, and one can customize network shapes for their need, by choosing various graph sampling methods, 3D network embedding methods and …

Learning Transferable Representations
A first contribution of this thesis is to propose causality as a language for problems of distribution shift. First, we consider domain generalisation, where no data from the test distribution are observed during training. What assumptions can be made regarding the relation between train and test …

Decomposition of Certain Representations Into A Direct Sum of Indecomposable Representations
Representations of quivers and posets are produced by persistent homology. It is possible to decompose such representations into direct sums of indecomposable representations. The indecomposable representations of quivers and posets that arise from one dimensional persistent homology are well …

Representations of McLain Groups
Basic modules of McLain groups are defined and investigated. These are a (possibly infinite dimensional) generalization of Andre’s basic modules of the multiplicative group of upper triangular square matrices over a finite field with 1’s on the main diagonal. The ring R need not be finite or …

Metric Representations Of Networks
… as a solid foundation for the theory of metric representations of networks. We begin by focusing on hierarchical clustering of asymmetric networks, which can be framed as a network projection problem onto ultrametric spaces. We show that the set of admissible methods is infinite but bounded in a …

Numeric Memory: Developing Representations
… link between children’s linear numeric magnitude representations and single number recall is confounded neither by age nor by memory span. Somewhat surprisingly, a number of “non-mapping” children failed to map non-symbolic and symbolic quantities on 3 numeric tasks (i.e., give-a-number task, …

Language-Mediated Event Representations
… not). The most reliable finding was that both representations of the moved object were less accessible on mention when associated with two event models (vs. one event model), suggesting that competition occurs between event models prior to access for a target if the target is represented across …

Representations of Elizabeth I
… I have sought to examine some contemporary representations of Elizabeth I. Beginning with an outline of how the queen struggled to construct her feminine power within and beyond dominant patriarchal discourse, I go on to explore closely three modern filmic treatments of the queen: The Virgin …

Knowledge representations for sensemaking
… the design and implementation of three knowledge representations systems for sensemaking. The focus is on the tension that exists between a knowledge representation's role as a surrogate for the world and its role as a facilitator of computational reasoning. Each system accepts natural language …

On total Springer representations

Contrastive Learning of Auditory Representations
Learning rich visual representations using contrastive self-supervised learning has been extremely successful. However, it is still a major question whether we could use a similar approach to learn more efficient auditory and audio-visual representations. In this thesis, we expand on prior …

Reflection arrangements and ribbon representations
Ehrenborg and Jung recently related the order complex for the lattice of d-divisible partitions with the simplicial complex of pointed ordered set partitions via a homotopy equivalence. The latter has top homology naturally identified as a Specht module. Their work unifies that of Calderbank, …

Numerical representations of fluid mixing
The work contained within this thesis is concerned with a theoretical investigatiop of both laminar and thermally driven types of cavity flow, together with an analysis of their associated mixing processes which find applications to Industrial mixing and also to the environment. The mixing …

REDUCIBILITY OF PARABOLICALLY INDUCED REPRESENTATIONS
… TITLE: REDUCIBILITY OF PARABOLICALLY INDUCED REPRESENTATIONS MAJOR PROFESSOR: Dr. D. Ban Reducibility of parabolically induced representations of $p$-adic groups is one of the basic questions in the representation theory, and generally a hard question. This paper presents how to reduced this …

Weil Representations of Unitary Groups
Let A be a finite, commutative, local and principal ideal ring, with maximal ideal r, endowed with an involution , possibly trivial, and let R be the fixed ring of . We distinguish three types of extensions A=R: symplectic, when is trivial and A = R; unramified, when the involution that induces on …
