Free resolutions, combinatorics, and geometry
Boij-Söderberg theory is the study of two cones: the first is the cone of graded Betti tables over a polynomial ring, and the second is the cone of cohomology tables of coherent sheaves over projective space. Each cone has a triangulation induced from a certain partial order. Our first result gives …

Syzygy Decompositions and Projective Resolutions
… syzygy module of 𝛬 as an 𝛬<SUP>𝑒</SUP> module. Resolutions of right 𝛬 modules 𝑀<SUB>𝛬</SUB> may be obtained by tensoring 𝑀 over 𝛬 with this bimodule resoution. We describe how to obtain such a resolution when 𝑀 is simple or when 𝑀 is given in the form of a projective presentation. Computations …

Parallel kinetic resolutions using active esters
… method of achieving this. Parallel kinetic resolutions are an interesting variation on the more classical resolution methods; this method has been recently introduced to the scientific community by Vedejs and there are currently very few examples of successful parallel kinetic resolutions in …

Variation resolutions for CMOS sensing networks
proposed circuits can be combined with other techniques including high-Q impedance matching for input voltage boosting and hierarchical tandem stages for further improvement on operating conditions. With a Q=10 matching network, -27 dBm sensitivity and 22% efficiency can be achieved for about 0.5 V …

Projective Resolutions of Generic Order Ideals
Let Y$\sp{\rm (n)}$ be the 1 x n matrix containing indeterminate entries $\{$Y$\sb1,\dots$,Y$\sb{\rm n}\}$ and X$\sp{\rm (n)}$ be the n x n alternating matrix containing indeterminate entries $\{$X$\sb{\rm ij}\vert$1 $\leq$ i $<$ j $\leq$ n$\}$, where we adopt the convention that X$\sb{\rm ii}$ = 0 …

Koszul Homology and Resolutions over Commutative Rings
… between Koszul homology and minimal free resolutions in various settings. We provide tools which allow one to view Koszul homology in a concrete way, and use these tools in a number of applications.</p> <p>One setting in which we examine Koszul homology is provided by the notion of …

The eleven dimensional supergravity equations, resolutions and Lefschetz fiber metrics
This thesis consists of three parts. In the first part, we study the eleven dimensional supergravity equations on B 7 x S 4 considered as an edge manifold. We compute the indicial roots of the linearized system using the Hodge decomposition, and using the edge calculus and scattering theory we …
