On non-defectivity of certain Segre-Veronese varieties
Let Xm,n be the Segre-Veronese variety Pm ×Pn embedded by the morphism given by O(1, 2) and let σs(Xm,n) denote the sth secant variety to Xm,n. In this paper, we prove that if m ...

On the Dimensionality of Face Space
The dimensionality of face space is measured objectively in a psychophysical study. Within this framework we obtain a measurement of the dimension for the human visual system. Usi...

Comparison of Picard groups in dimension 1
We compare two Picard groups in dimension one. Our proofs are constructive and the results generalize a theorem of J. Sands [11]. MSC 2000: 13C15, 13C20, 03F65, 13F45

Intrinsic dimension of a dataset: what properties does one expect?
— We propose an axiomatic approach to the concept of an intrinsic dimension of a dataset, based on a viewpoint of geometry of high-dimensional structures. Our first axiom postul...

Turing degrees of reals of positive effective packing dimension
A relatively longstanding question in algorithmic randomness is Jan Reimann's question whether there is a Turing cone of broken dimension. That is, is there a real A such that...
