Stratifying Quotient Stacks and Moduli Stacks [PDF]
, 2018 Recent results in geometric invariant theory (GIT) for non-reductive linear algebraic group actions allow us to stratify quotient stacks of the form [X/H], where X is a projective scheme and H is a linear algebraic group with internally graded unipotent radical acting linearly on X, in such a way that each stratum [S/H] has a geometric quotient S/H ...

Efficient plotting the functions with discontinuities based on combined sampling
Geoinformatics FCE CTU, 2018 This article presents new algorithm for interval plotting ofthe function $y=f(x)$ based on the combined sampling. The proposedmethod synthesizes uniform and adaptive sampling approaches and providesa more compact and efficient function representation ...

Two-stack-sorting with pop stacks
Australas. J Comb., 2018 We consider the set of permutations that are sorted after two passes through a pop stack. We characterize these permutations in terms of forbidden patterns (classical and barred) and enumerate them according to the ascent statistic. Then we show these permutations to be in bijection with a special family of polyominoes.

Experimental Investigation on the Thermoacoustic Effect in Easily Accessible Porous Materials
Energies, 2020 Thermoacoustic devices are the systems which use acoustic power to transport heat through a stack in a resonance tube. The stack is one of the most important parts of the thermoacoustic systems.

Agentic AI in Cloud-Based Credit Card Fraud Detection: Towards Autonomous Risk Mitigation
ITEGAM-JETIACredit card fraud (CCF) still remains an ongoing concern for financial institutions because to the huge disparity between genuine and fraudulent transactions, as well as the ever-changing behavior of fraudsters. This paper proposes a cloud-based Agentic

MOTIVIC INVARIANTS OF ARTIN STACKS AND 'STACK FUNCTIONS' [PDF]
The Quarterly Journal of Mathematics, 2007 An invariant I of quasiprojective K-varieties X with values in a commutative ring R is "motivic" if I(X)= I(Y)+I(X\Y) for Y closed in X, and I(X x Y)=I(X)I(Y). Examples include Euler characteristics chi and virtual Poincare and Hodge polynomials. We first define a unique extension I' of I to finite type Artin K-stacks F, which is motivic and satisfies ...

Mapping stacks of topological stacks [PDF]
Journal für die reine und angewandte Mathematik (Crelles Journal), 2010 We prove that the mapping stack Map(Y,X) of topological stacks X and Y is again a topological stack if Y admits a compact groupoid presentation. If Y admits a locally compact groupoid presentation, we show that Map(Y,X) is a paratopological stack. In particular, it has a classifying space (hence, a natural weak homotopy type).
