Tags
A tag is a keyword or label that categorizes your question with other, similar questions.
Use this tag for questions about advanced computing to model, simulate, understand, or solve engineering, biological, physical, social, and humanities problems.

Pushdown automata are a type of automata that employ stacks. They are more capable than finite state automata but less capable than Turing machines. The term "pushdown" refers to the fact that the stack can be regarded as being "pushed down" like a tray dispenser at a cafeteria, since the operations never work on elements other than the top element.
To be used with [automata].

This tag is for questions of Finite-Duration Solutions to Differential Equations, which after an ending time by itself becomes zero forever after. For ordinary functions which have a starting and ending time, see [tag:piecewise-continuity], and if time is not the involved variable, search for [tag:compact-support]. Finite-Duration solution cannot be solutions of Linear ODE, since they fail uniqueness. Synonyms: [tag:finite-time], [tag:time-limited]

For mathematical questions about CVXPY; questions purely about the language, syntax, or runtime errors would likely be better received on Stack Overflow. CVXPY is a Python-embedded modeling language for convex optimization problems.

Contact geometry is a subfield of differential geometry, focusing on contact manifolds, which are differentiable manifolds endowed with some codimension 1 distribution that is maximally non-integrable.

For questions about the so-called slowly varying functions, usually defined on the positive real line and whose "variation" is small (in particular, they grow slower than any power). This class contains, for example, all the powers of logarithms.

The $p$-Laplacian, or the $p$-Laplace operator, is a quasilinear elliptic partial differential operator of second order. It is a nonlinear generalization of the Laplace operator, where $ p $ is allowed to range over $ 1 < p < \infty $.

Hilbert C*-modules are mathematical objects which generalise the notion of a Hilbert space (which itself is a generalisation of Euclidean space), in that they endow a linear space with an "inner product" which takes values in a C*-algebra
