 minimal-surfaces× 29 Question on minimal surfaces, or surfaces that have zero mean curvature. vector-space-isomorphism× 29 wave-equation× 28 For questions related to solutions and analysis of the wave equation. poker× 28 a card game with several variants (Draw, Texas Hold'em, ...), the common goal being to collect face value patterns such as "four of a kind", "full house" or "straight" or all of a suit ("flus… statistical-mechanics× 28 classifying-spaces× 28 A classifying space $BG$ of a topological group $G$ is the quotient of a weakly contractible space $EG$ by a free action of $G$. When $G$ is a discrete group $BG$ has homotopy type of $K(G,1)$ and (co… calendar-computations× 28 for questions about combinatorial and computational issues with regards to calendar systems. A typical, well-known mathematical result in this direction is John Conway's Doomsday Algorithm… co-algebra× 27 algebraic-identities× 27 cw-complexes× 27 inverse-problems× 27 Inverse problems involve for example reconstruction of an object based on physical measurements and finding a best model/parameters out of a family given observed data. Typically the corresponding "fo… separation-axioms× 27 properties of topological space which, roughly speaking, say in what way two points, a point and a closed set, or two closed sets can be "separated". transfinite-recursion× 27 Questions dealing with set-theoretic functions defined by transfinite recursion. searching× 27 For questions about various search algorithms. quantum-computation× 27 quotient-spaces× 27 voting-theory× 27 For questions regarding the mathematical analysis of voting systems and behavior. Examples include the median voter theorem or the Condorcet jury theorems. primitive-roots× 26 satisfiability× 26 For questions on the subject of "satisfiability", that is, whether there exists an interpretation/model in which a given (logical) formula is true. ricci-flow× 26 The Ricci flow on a Riemannian manifold $(M,g)$ is determined by the geometric evolution equation $\partial_t g_{ij} = -2R_{ij}$ where $R_{ij}$ is the Ricci curvature. The Ricci flow is the main ingre… ratio× 26 planar-graph× 26 minimal-polynomials× 26 the lowest order monic polynomial satisfied by an object, such as a matrix or an algebraic element over a field. stationary-processes× 26 For questions about strictly stationary or stationary in the wide sense sequences or processes. Questions about deterministic stationary processes (in the case of discrete dynamical systems) are welco… homogeneous-equation× 26 extrapolation× 26 For question on extrapolation, the process of estimating, beyond the original observation interval. gauge-theory× 26 galois-representations× 26 direct-sum× 26 binary-operations× 26 gauss-sums× 25 For questions on Gauss sums, a particular kind of finite sum of roots of unity. topological-graph-theory× 25 For questions about topological graph theory. nets× 25 a generalization of a sequence where a directed set is used as the index set instead of positive integers. Convergence of nets can be defined in a similar way as convergence of sequences. … semidirect-product× 25 a construction in group theory generalizing the direct product. It arises as the structure of a group $G$ with a normal subgroup $N$ having a complement $N$. q-analogs× 25 for questions pretaining to q-analogs of functions, for example q-Binomials, $q$-derivatives, the q-theta function, the q-Pochammer symbol, etc. quasicoherent-sheaves× 24
