Strongly Consistent Density Estimation of Regression Redidual
[OWP201207] (Mathematisches Forschungsinstitut Oberwolfach, 2012)Consider the regression problem with a response variable $Y$ and with a $d$dimensional feature vector $X$. For the regression function $m(x) = \mathbb{E}\{YX = x\}$, this paper investigates methods for estimating the ...

2215a  StructurePreserving Discretizations for Nonlinear Systems of Hyperbolic, InvolutionConstrained Partial Differential Equations on Manifolds
[OWR202219] (2022)  (10 Apr  16 Apr 2022)The topic of this workshop was the study of mathematical and numerical analysis for involutionconstrained hyperbolic partial differential equations on manifolds. An example is the positivity of the density for the ... 
1309  Structured Function Systems and Applications
[OWR201311] (2013)  (24 Feb  02 Mar 2013)Quite a few independent investigations have been devoted recently to the analysis and construction of structured function systems such as e.g. wavelet frames with compact support, Gabor frames, refinable functions in the ... 
A study on gradient blow up for viscosity solutions of fully nonlinear, uniformly elliptic equations
[OWP200910] (Mathematisches Forschungsinstitut Oberwolfach, 20090304)We investigate sharp conditions for boundary and interior gradient estimates of continuous viscosity solutions to fully nonlinear, uniformly elliptic equations under Dirichlet boundary conditions. When these conditions are ... 
1944  Subfactors and Applications
[OWR201949] (2019)  (27 Oct  02 Nov 2019)The theory of subfactors connects diverse topics in mathematics and mathematical physics such as tensor categories, vertex operator algebras, quantum groups, quantum topology, free probability, quantum field theory, ... 
1513  Subfactors and Conformal Field Theory
[OWR201516] (2015)  (22 Mar  28 Mar 2015)Connections between subfactor theory and conformal field theory have been expected since the early days of the former in 1980’s, and recently we see more and more evidence for deeper relations. It was our aim to attract ... 
The Subgroup Structure of PseudoReductive Groups
[OWP202408] (Mathematisches Forschungsinstitut Oberwolfach, 20240731)Let $k$ be a field. We investigate the relationship between subgroups of a pseudoreductive $k$group $G$ and its maximal reductive quotient $G'$, with applications to the subgroup structure of $G$. Let $k'/k$ be the minimal ... 
1825a  Subgroups of Cremona Groups
[OWR201828] (2018)  (17 Jun  23 Jun 2018)There have been recent breakthroughs in two related questions: the study of Cremona groups, and the problem of rationality of algebraic varieties. Our workshop brought together algebraic geometers, who discussed and tried ... 
Supertropical linear algebra
[OWP201014] (Mathematisches Forschungsinstitut Oberwolfach, 2010)The objective of this paper is to lay out the algebraic theory of supertropical vector spaces and linear algebra, utilizing the key antisymmetric relation of "ghost surpasses." Special attention is paid to the various ... 
Supertropical Matrix Algebra III : Powers of Matrices and Generalized Eigenspaces
[OWP201020] (Mathematisches Forschungsinstitut Oberwolfach, 2010)We investigate powers of supertropical matrices, with special attention to the role of the coefficients of the supertropical characteristic polynomial (especially the supertropical trace) in controlling the rank of a power ... 
Supertropical Quadratic Forms I
[OWP201327] (Mathematisches Forschungsinstitut Oberwolfach, 2013)We initiate the theory of a quadratic form q over a semiring $R$. As customary, one can write $q(x+y)=q(x)+q(y)+b(x,y)$, where b is a companion bilinear form. But in contrast to the ringtheoretic case, the companion ... 
Supertropical semirings and supervaluations
[OWP201005] (Mathematisches Forschungsinstitut Oberwolfach, 2010)We interpret a valuation $\upsilon$ on a ring $R$ as a map $\upsilon:R \rightarrow M$ into a so called bipotent semiring $M$ (the usual maxplus setting), and then define a supervaluation $\varphi$ as a suitable map into ... 
Sur le Minimum de la Fonction de Brjuno
[OWP201826] (Mathematisches Forschungsinstitut Oberwolfach, 20181211)The Brjuno function attains a strict global minimum at the golden section.
