Simplicial and Cellular Trees
(Springer International Publishing, 20160416)Much information about a graph can be obtained by studying its spanning trees. On the other hand, a graph can be regarded as a 1dimensional cell complex, raising the question of developing a theory of trees in higher ... 
A NonPartitionable CohenMacaulay Simplicial Complex
(Elsevier, 20160820)A longstanding conjecture of Stanley states that every Cohen–Macaulay simplicial complex is partitionable. We disprove the conjecture by constructing an explicit counterexample. Due to a result of Herzog, Jahan and Yassemi, ... 
Cuts and flows of cell complexes
(Springer Verlag, 20141015)We study the vector spaces and integer lattices of cuts and flows associated with an arbitrary finite CW complex, and their relationships to group invariants including the critical group of a complex. Our results extend ... 
Enumerating Colorings, Tensions and Flows in Cell Complexes
(Elsevier, 201402)We study quasipolynomials enumerating proper colorings, nowherezero tensions, and nowherezero flows in an arbitrary CWcomplex X, generalizing the chromatic, tension and flow polynomials of a graph. Our colorings, tensions ... 
Pseudodeterminants and Perfect Square Spanning Tree Counts
(International Press, 201506)The pseudodeterminant pdet(M) of a square matrix is the last nonzero coe cient in its characteristic polynomial; for a nonsingular matrix, this is just the determinant. If @ is a symmetric or skewsymmetric matrix then ... 
A special Riemann surface with application to the hyperelliptic case
(University of Kansas, 1915) 
The principle of duality in a projective space of N dimensions
(University of Kansas, 1922.) 
Projective normality and higher syzygies for algebraic surfaces
(De Gruyter Open, 19990305)In this work we develop new techniques to compute Koszul cohomology groups for several classes of varieties. As applications we prove results on projective normality and syzygies for algebraic surfaces. From more general ... 
Erratum to Projective normality and higher syzygies for algebraic surfaces
(De Gruyter Open, 19990605) 
On the Stochastic Burgers’ Equation in the Real Line
(Institute of Mathematical Statistics, 19990101)In this paper we establish the existence and uniqueness of an L2(R) valued solution for a onedimensional Burgers’ equation perturbed by a space–time white noise on the real line. We show that the solution is continuous ... 
Some results on rational surfaces and Fano varieties
(De Gruyter, 20010123) 
Nucleation and propagation of phase mixtures in a bistable chain
(American Physical Society, 20090429)We consider a prototypical discrete model of phase transitions. The model consists of a chain of particles, each interacting with its nearest and nexttonearest neighbors. The longrange interaction between nexttonearest ... 
Spectral Stability for Subsonic Traveling Pulses of the Boussinesq “abc" System

Backward Stochastic Differential Equations and FeynmanKac Formula for Lévy Processes, with Applications in Finance

Power variation of some integral fractional processes
(Bernoulli Society for Mathematical Statistics and Probability, 20060801)We consider the asymptotic behaviour of the realized power variation of processes of the form ∫^(t)(0)u(s)dB^(H)(s), where B^H is a fractional Brownian motion with Hurst parameter H∈(0,1), and u is a process with finite ... 
Hitting Times for Gaussian Processes
(Institute of Mathematical Statistics, 20080101)See article for abstract. 
The Relation Between the QR and LR Algorithms
(Society for Industrial and Applied Mathematics, 19980605)For an Hermitian matrix the QR transform is diagonally similar to two steps of the LR transforms. Even for nonHermitian matrices the QR transform may be written in rational form.
