Conceptual Spaces: The Geometry of Thought

Inside cognitive technology, techniques at present dominate the matter of modeling representations. The symbolic technique perspectives cognition as computation regarding symbolic manipulation. Connectionism, a distinct case of associationism, types institutions utilizing synthetic neuron networks. Peter Gardenfors deals his conception of conceptual representations as a bridge among the symbolic and connectionist methods.

Decorated Teichmuller Theory

There's an primarily “tinker-toy” version of a trivial package over the classical Teichmüller house of a punctured floor, known as the adorned Teichmüller house, the place the fiber over some extent is the distance of all tuples of horocycles, one approximately each one puncture. This version results in an extension of the classical mapping classification teams known as the Ptolemy groupoids and to yes matrix versions fixing comparable enumerative difficulties, each one of which has proved valuable either in arithmetic and in theoretical physics.

The Lin-Ni's problem for mean convex domains

The authors turn out a few subtle asymptotic estimates for optimistic blow-up options to $\Delta u+\epsilon u=n(n-2)u^{\frac{n+2}{n-2}}$ on $\Omega$, $\partial_\nu u=0$ on $\partial\Omega$, $\Omega$ being a gentle bounded area of $\mathbb{R}^n$, $n\geq 3$. specifically, they express that focus can happen merely on boundary issues with nonpositive suggest curvature whilst $n=3$ or $n\geq 7$.

Such a machinery is at hand: it is the flexion structure, which arose in the early 90s in the context of singularity analysis, more precisely in the investigation of parametric or “co-equational” resurgence.
