Sumset Lower Bounds In Abelian Groups, Van T. Huynh

Honors Theses

This thesis investigates sumset lower bounds across discrete and continuous settings. We begin with general inequalities in torsion-free abelian groups and then specialize to the integers modulo prime p, where we present the Cauchy–Davenport Theorem, which establishes the bound ∣A+B∣≥min(p,∣A∣+∣B∣−1). The equality case is further examined via Vosper's Theorem, which characterizes subsets attaining this bound as arithmetic progressions under suitable conditions. The continuous analogue in Euclidean spaces is then considered, where cardinality is replaced by Lebesgue measure. In this setting, the Brunn–Minkowski Inequality provides a sharp lower bound for the Lebesgue measure of A+B and serves as a geometric counterpart …

Reimagining The Cadenza: Bluegrass And Mozart, Linna Zheng

Honors Theses

The bluegrass-inspired cadenza for the first movement of Mozart’s Violin Concerto No. 5 is a parallel with the “Turkish” episode of Mozart’s composition. While introducing the bluegrass idiom into a Classical concerto may not be idiosyncratic, it can be understood and seen as an extension of Mozart’s own practice and approach to stylistic disruption. This approach can be understood through the concepts of Sonata Theory, revealing the cadenza as a site of productive deformation within a normative formal framework. Along with this, Robert S. Hatten’s concept of troping further supports the idea that the interaction between Classical and bluegrass idioms …
