Definition as written by Terry:
The philosophy of layering your composting materials and alternating between browns and greens is common among all methods. Lasagna composting is done "in place" in the bed you would eventually add compost to, when the compost is done.
The lasagna method has advantages for gardeners who may not have the stamina or desire to haul their compost from a bin to their beds, as well as allowing gardeners on small plots to amend their soil with compost even though they don't have space for a compost bin or pile.
Since a lasagna compost is typically allowed to break down without being turned and worked, it can take longer to break down than an actively worked compost pile. And since the initial layering requires creating a stack of materials that is upwards of two feet tall, it isn't suited for beds that have perennials or shrubs already in place.
(And in case you're wondering, the final composted material will be much smaller in volume than when you start!)
Other similar methods are called no-dig gardening or interbay mulching or sheet composting
