 Description:
A fundamental problem in algebraic geometry is to decompose the solution set of a given polynomial system. A numerical description of this solution set is called a numerical irreducible decomposition and currently all standard algorithms use a sequence of homotopies forming a dimensionbydimension approach. In this article, we pair a classical result to compute a smooth point on every irreducible component in every dimension using a single homotopy together with the theory of isosingular s…

 Description:
In the field of numerical algebraic geometry, positivedimensional solution sets of systems of polynomial equations are described by witness sets. In this paper, we define multiprojective witness sets which encode the multidegree information of an irreducible multiprojective variety. Our main results generalize the regeneration solving procedure, a trace test, and numerical irreducible decomposition to the multiprojective case. Examples are included to demonstrate this new approach.

 Description:
Standard interior point methods in semidefinite programming track a solution path for a homotopy defined by a system of polynomial equations. By viewing this in the context of numerical algebraic geometry, we are able to employ techniques to handle various cases which can arise. Adaptive precision path tracking techniques can help navigate around illconditioned areas. When the optimizer is singular with respect to the firstorder optimality conditions, endgames can be used to efficiently and…

 Description:
A common problem when analyzing models, such as a mathematical modeling of a biological process, is to determine if the unknown parameters of the model can be determined from given inputoutput data. Identifiable models are models such that the unknown parameters can be determined to have a finite number of values given inputoutput data. The total number of such values over the complex numbers is called the identifiability degree of the model. Unidentifiable models are models such that th…

 Description:
Computational tools in numerical algebraic geometry can be used to numerically approximate solutions to a system of polynomial equations. If the system is wellconstrained (i.e., square), Newton’s method is locally quadratically convergent near each nonsingular solution. In such cases, Smale’s alpha theory can be used to certify that a given point is in the quadratic convergence basin of some solution. This was extended to certifiably determine the reality of the corresponding sol…

 Description:
The Mexican patent database collects data on all patents issued in Mexico from roughly 1840 to the onset of the Mexican Revolution in 1911, totaling approximately thirteen thousand five hundred (13,500) discrete patent records. At present, this is the most comprehensive record of patents issued by Mexican governments during the nineteenth century. There is no single archival or published source that contains a comprehensive list or data on Mexican patents issued over the course of the long …

 Description:
This dataset contains data from 17 stream 15NNH4 tracer addition experiments conducted globally, with data partitioned by autotrophic uptake compartments (i.e., epilithic biofilm, filamentous algae, bryophytes/macrophytes) and heterotrophic uptake compartments (i.e., leaves, small wood, and fine particles) that comprise the base of stream food webs. The dataset includes compartmental data on N biomass and uptake as well as other physiochemical variable that describe conditions in each stream.
