Categorical resolutions of irrational singularities
Alexander Kuznetsov, Valery A. Lunts
We show that the derived category of any singularity over a field of characteristic 0 can be embedded fully and faithfully into a smooth triangulated category which has a semiortho…
The Yang-Mills theory as a massless limit of a massive nonabelian gauge model
A. A. Slavnov
A gauge invariant infrared regularization of the Yang-Mills theory applicable beyond perturbation theory is constructed.
On geometric interpretation of the Aharonov-Bohm effect
M. O. Katanaev
A geometric interpretation of the Aharonov--Bohm effect is given in terms of connections on principal fiber bundles. It is demonstrated that the principal fiber bundle can be trivi…
On geometric interpretation of the Berry phase
M. O. Katanaev
A geometric interpretation of the Berry phase and its Wilczek--Zee non-Abelian generalization are given in terms of connections on principal fiber bundles. It is demonstrated that…
Ga-actions on affine cones
Takashi Kishimoto, Yuri Prokhorov, Mikhail Zaidenberg
We give a criterion of existence of a unipotent group action on the affine cone over a projective variety or, more generally, on the affine quasicone over a variety which is projec…
Reversibility of a quantum channel: general conditions and their applications to Bosonic linear channels
M. E. Shirokov
The method of complementary channel for analysis of reversibility (sufficiency) of a quantum channel with respect to families of input states (pure states for the most part) are co…
