Multigraded commutative algebra of graph decompositions
The toric fiber product is a general procedure for gluing two ideals, homogeneous with respect to the same multigrading, to produce a new homogeneous ideal. Toric fiber products generalize familiar
Noetherianity for infinite-dimensional toric varieties
We consider a large class of monomial maps respecting an action of the infinite symmetric group, and prove that the toric ideals arising as their kernels are finitely generated up to symmetry. Our
Goodness of fit for log-linear network models: dynamic Markov bases using hypergraphs
TLDR
A dynamic approach to explore the fiber of a model is presented, which is based on the combinatorics of hypergraphs arising from the toric algebra structure of log-linear models and allows for reciprocation effects.

Degree Bounds for a Minimal Markov Basis for the Three-State Toric Homogeneous Markov Chain Model
We study the three state toric homogeneous Markov chain model and three special cases of it, namely: (i) when the initial state parameters are constant, (ii) without self-loops, and (iii) when both
A Markov basis for two-state toric homogeneous Markov chain model without initial parameters
We derive a Markov basis consisting of moves of degree at most three for two-state toric homogeneous Markov chain model of arbitrary length without parameters for initial states. Our basis consists
Markov degree of the three-state toric homogeneous Markov chain model
We consider the three-state toric homogeneous Markov chain model (THMC) without loops and initial parameters. At time $$T$$T, the size of the design matrix is $$6 \times 3\cdot 2^{T-1}$$6×3·2T-1 and

Toric geometry of cuts and splits
Associated to any graph is a toric ideal whose generators record relations among the cuts of the graph. We study these ideals and the geometry of the corresponding toric varieties. Our theorems and
Cut ideals of K4-minor free graphs are generated by quadrics
Cut ideals are used in algebraic statistics to study statistical models defined by graphs. Intuitively, topological restrictions on the graphs should imply structural statements about the
Ideals of Graph Homomorphisms
In combinatorial commutative algebra and algebraic statistics many toric ideals are constructed from graphs. Keeping the categorical structure of graphs in mind we give previous results a more

We construct Markov chain algorithms for sampling from discrete exponential families conditional on a sufficient statistic. Examples include contingency tables, logistic regression, and spectral
