Descriptive Complexity for counting complexity classes
(IEEE, 2017)
Descriptive Complexity has been very successful in characterizing complexity classes of decision problems in terms of the properties definable in some logics. However, descriptive complexity for counting complexity classes, ...
A Simplicial Complex is Uniquely Determined by Its Set of Discrete Morse Functions
(Springer, 2017-07)
We prove that a connected simplicial complex is uniquely determined by its complex of discrete Morse functions. This settles a question raised by Chari and Joswig. In the 1-dimensional case, this implies that the complex ...
The Complexity–Stability Debate, Chemical Organization Theory, and the Identification of Non-classical Structures in Ecology
(Springer, 2020-03)
We present a novel approach to represent ecological systems using reaction networks, and show how a particular framework called chemical organization theory (COT) sheds new light on the longstanding complexity–stability ...
De PH a IP : un curso en complejidad computacional
(2019-11)
En este trabajo estudiamos algunas de las clases más importantes de la teoría de Complejidad Computacional. Nos basamos en el programa que propone el libro Computational Complexity a modern approach, del cual vemos la ...
Analyzing and modeling real-world phenomena with complex networks: a survey of applications
(Taylor and FrancisAbingdon, 2011-05)
The success of new scientific areas can be assessed by their potential in contributing to new theoretical approaches and in applications to real-world problems. Complex networks have fared extremely well in both of these ...
On the complexity of computing estimates of condition measures of a conic linear system
(INST OPERATIONS RESEARCH MANAGEMENT SCIENCES, 2003)
Condition numbers based on the "distance to ill-posedness" rho(d) have been shown to play a crucial role in the theoretical complexity of solving convex optimization models. In this paper, we present two algorithms and ...
Axial ligand influence on geometries, charge distributions and electronic structures of iron tetraazamacrocycle [Fe((II))TIM(X)(Y)](2+) complexes assessed by Density Functional Theory
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
We employed the Density Functional Theory along with small basis sets, B3LYP/LANL2DZ, for the study of FeTIM complexes with different pairs of axial ligands (CO, H(2)O, NH(3), imidazole and CH(3)CN). These calculations did ...
