2. Topological and Shifting Theoretic Methods in Combinatorics and Algebra
Abstract : This thesis consists of six papers related to combinatorics and commutative algebra.In Paper A, we use tools from topological combinatorics to describe the minimal free resolution of ideals with a so called regular linear quotient. Our result generalises the pervious results by Mermin and by Novik, Postnikov & Sturmfels. READ MORE

3. Graphical representations of Ising and Potts models : Stochastic geometry of the quantum Ising model and the space-time Potts model
Abstract : HTML clipboard Statistical physics seeks to explain macroscopic properties of matter in terms of microscopic interactions. Of particular interest is the phenomenon of phase transition: the sudden changes in macroscopic properties as external conditions are varied. READ MORE

4. On Face Vectors and Resolutions
Abstract : This thesis consist of the following three papers.Convex hull of face vectors of colored complexes. In this paper we verify a conjecture by Kozlov (Discrete ComputGeom18(1997) 421–431), which describes the convex hull of theset of face vectors ofr-colorable complexes onnvertices. READ MORE

5. Simplicial Complexes of Graphs
Abstract : Let G be a finite graph with vertex set V and edge set E. A graph complex on G is an abstract simplicial complex consisting of subsets of E. In particular, we may interpret such a complex as a family of subgraphs of G. READ MORE
