Tubular Field Theory
K. -I. Izawa
We propose tubular field theory, which is a continuum analogue of lattice field theory. One-dimensional links (and zero-dimensional sites) in lattice field theory are replaced by t…

Quintessential Vanishing of the Cosmological Constant
K. -I. Izawa
We consider an effective field theory description of gravity coupled to a scalar field with volume-preserving diffeomorphism and Weyl invariances. The smallness of the cosmological…

Primary Inflation
K. -I. Izawa
We consider an inflationary universe scenario with multiple stages of inflation. The primary inflation, which may start at the Planck epoch, is followed by secondary inflations, wh…
