DESCRIPTION:Speakers: Kirill Bronnikov (VNIIMS)\nIn 6D general relativity 
 with a scalar field as a source of gravity\, a new type of static wormhole
  solutions is presented: such wormholes connect our universe with a small 
 2D extra subspace with a universe where this extra subspace is large. We c
 onsider manifolds\nwith the structure M0 x M1 x M2\, where M0 is 2D Lorent
 zian space-time while each of M1 and M2 can be a 2-sphere or a 2-torus. Af
 ter selecting possible asymptotic behaviors of the metric functions compat
 ible with the field equations\, we give explicit examples of wormhole solu
 tions with spherical symmetry in our space-time and toroidal extra dimensi
 ons. In one example\, with a massless scalar field (it is a special case o
 f a well-known more general solution)\, the extra dimensions have a large 
 constant size at the "far end"\;\nthe other example contains a nonzero sca
 lar field potential which provides a 6D anti-de Sitter asymptotic behavior
 \, where all spatial dimensions are infinite.\n\nhttps://indico.particle.m
