We give a sufficient condition for a first order infinitesimal deformation of a curve on a 3-fold to be obstructed. As application we construct generically non-reduced components of the Hilbert schemes of uniruled 3-folds and the Hom scheme from a general curve of genus five to a general cubic 3-fold.

We consider a family of slightly extended version of the Raynaud’s surfaces X over the field of positive characteristic with Mumford-Szpiro type polarizations Z, which have Kodaira non-vanishing H(X,Z) 6= 0. The surfaces are at least normal but smooth under a special condition. We compute the cohomologies H(X,Z) for i, n ∈ Z and study their (non-)vanishing. Finally, we give a fairly large famil...

By a combination of geometrical and configurational analysis we study the properties of absolute minimal and equilibrium states of general Mumford-Shah functionals, with applications to models of quasistatic brittle fracture propagation. The main results concern the mathematical relations between physical quantities as energy release rate and energy concentration for 3D cracks with complex shap...

Arguing against the claim that every dispositional property is grounded in some property other than itself, Stephen Mumford presents what he calls the ‘Ungrounded Argument’. If successful, the Ungrounded Argument would represent a major victory for anti-Humean metaphysics against its Humean rivals, as it would allow for the existence of primitive modality. Unfortunately, Humeans need not yet be...

In 2005, reviewed current research literature in view morphing and matching for single views, and discussed a feature based approach to sparse view morphing that also shows promise for compression of the model data corpus. Worked on a new Bayesian approach for the problem from a mid-level segmentation problem. We obtained good results for feature-based morphing, as well as preliminary demonstra...
