Informal Logic, 2009 Numerous informal logicians and argumentation theorists restrict their theorizing to what they call “real” arguments. But is there a clear distinction to be made between “real” and “non-real” arguments?

Simplicity of tangent bundles of smooth horospherical varieties of Picard number one
Comptes Rendus. Mathématique, 2022 Recently, Kanemitsu has discovered a counterexample to the long-standing conjecture that the tangent bundle of a Fano manifold of Picard number one is (semi)stable. His counterexample is a smooth horospherical variety.

A controllability counterexample [PDF]
IEEE Transactions on Automatic Control, 2005 Simulation by time discretizations can be qualitatively misleading; as counterexamples a class of noncontrollable single-input two-dimensional bilinear control systems is presented whose Euler discretizations are controllable on the punctured plane.

Do Counterexamples on the Kāraka Rules A. 1.4.33–36 in the Kāśikāvr̥tti Serve Any Purpose?
Bhasha, 2023 Ajotikar et al. (2016) claim that most of the counterexamples provided in the Kāśikāvr̥tti conform to the distinctive feature of a counterexample, namely, having all the conditions stated in the rule except one (ekāṅgavikalatā).

Minimizing Counterexample of ACTL Property [PDF]
, 2005 Counterexample minimization tries to remove irrelevant variables from counterexamples, such that they are easier to be understood. For the first time, we proposes a novel approach to minimize looplike and path-like counterexamples of ACTL properties. For

A NONSEPARABLE AMENABLE OPERATOR ALGEBRA WHICH IS NOT ISOMORPHIC TO A $C^*$ -ALGEBRA
Forum of Mathematics, Sigma, 2014 It has been a long-standing question whether every amenable operator algebra is isomorphic to a (necessarily nuclear) $\mathrm{C}^*$ -algebra.

A Counterexample to Comon's Conjecture [PDF]
SIAM Journal on Applied Algebra and Geometry, 2018 We present an example of a symmetric tensor of size $800\times 800\times 800$ which can be written a sum of $903$ simple tensors with complex entries but not as a sum of $903$ symmetric simple tensors.

Planar Turán Numbers of Cycles: A Counterexample [PDF]
, 2021 The planar Turan number exP(Cℓ,n) is the largest number of edges in an n-vertex planar graph with no ℓ-cycle. For ℓ∈{3,4,5,6}, upper bounds on exP(Cℓ,n) are known that hold with equality infinitely often. Ghosh, Györi, Martin, Paulo, and Xiao [arXiv:2004.
